Re: [Scilab-users] Scilab 6 Release

[Pablo Fonovich]

Hi,
As far as i know, scilab asks for your information after the download has 
started. At least, that's my case. Perhaps your browser is blocking the 
download?

Betreff: [Scilab-users] Scilab 6 Release

Dear Scilab users,

We are very happy to announce the release of Scilab 6.0.0.

The Scilab Team invested significant development efforts for the past years in 
order to release Scilab 6.
The goal with Scilab 6 is to address technological evolutions and new needs in 
terms of modeling and simulation from the scientific & engineering community.
This led our team to completely redevelop the computation core of Scilab in 
order to build a solid base combining performance and evolutivity.
The new aspects of Scilab 6 worth notifying are the following:

  *   New language parser & new core,
  *   New utilities for development productivity,
  *   Xcos block diagram improvement,
  *   Newsfeed - a communication channel with the users
Download it on Scilab.org

Scientifically yours

I'm still having trouble to use scilab 6.0.0 in Ubuntu 17.10. As i stated in

However the error is kinda strange, since Scilab doesn't use the Gimp
Toolkit (GTK). So I suspect it is something wrong with your environment /
desktop setting.


Yes, it could be. Anyway i'm not the only getting this error on ubuntu. See 
this link: https://www.scivision.co/install-scilab-linux/

Can you provide a minimal code snippet to reproduce?


t1 = 1225; t2 = 3245;
tau = 3/2 * ( t2 - t1 )
theta = t2 - tau

s=poly(0,'s')
G=syslin('c',1.72/(1+tau*s)*(2-s*theta)/(2+s*theta))
bode(G)


In console, it gives: Segmentation fault (core dumped) (ubuntu 16.04, scilab 6) 
In scilab 5.5.2 works fine the same code.

Hi:


First of all, i cannot run scilab 6.0 in Ubuntu 17.10, gives GTKLookAndFeel 
error that was adressed in the past, but not resolved.


Second, in my Ubuntu 16.04 PC, scilab 6.0 gives seg fault when trying to use

And last, is there a way to simulate a trasnfer function with delay using csim?

Hello,
Today, I checked again with the Lenovo T420 + Ubuntu 16.04 + SciLab 6 ... and I 
could NOT reproduce the bug (that I did observe with the same equipment and 
same code 5 months ago). Most probably, an (automatic) update of Ubuntu may 
have fixed the problem. But I don't know the name of the file tracking the 
changes in the update... If anyone knows, and can give me instructions, I would 
be happy to do it if it helps.

Re: [Scilab-users] add number arrays efficiently, how?

[Pablo Fonovich]

Hi,
I would have also written

SumArr = [SumArr toAdd]

Why is this answer different to the original?

SumArr( (length(SumArr)+1) : (length(SumArr)+length(toAdd)) ) = toAdd;

May be im missing something, but i think in both cases you need to know the 
arrays in advance, dont you?

Also, i think  SumArr = [SumArr toAdd] has better performance...
Perhaps im not understanding the question..

If you know them in advance, yes.  My answer was predicated on not
knowing "toAdd" at the same time as the 1x3 SumArr.

I was implementing a digital reverberation for a class, and i wanted to show 
that it was indeed a comb filter.. Thanks all of you! you helped me a lot.

Not sure what you're trying to achieve, but if you want a plot of the
linear amplitude response on a linear frequency line, use Horner:

H = syslin('d', (%z - 0.9) / (%z - 99));
th = %pi * (-1:0.01:1)';
clf; plot2d(th, abs(horner(H, exp(%i * th; xgrid(2)

Hi:

This is the first time i work with discrete time transfers functions and Scilab.

I want to use bode() for plotting the magnitud and phase response of the

This is what i'm doing:

S=syslin('d',H)

i get a warning that frequencies beyond nyquist rate are ignored and the

transform the normalized frecuency to herz the sample rate must be used, but i 
don't know how to pass it to the system or something.

S=syslin(dt,H) defines a dynamical system sampled. dt beeing the sampling 
period in second.
If you want the frequency uniis be in rd/s add "rad" as last input argument

Any hints would be appreciated.

Re: [Scilab-users] Simultaneous record and play sound with scilab

[Pablo Fonovich]

Thanks for your answer!


The idea was to do it all in scilab. I finally managed to get portaudio toolbox 
working... but it does not let you record and play at the same time.

I finally cheated and added 1sec delay to mi equipment (digital recorder) and 
put it in loopback mode, so with scilab i played a sound and then recorded the 
delayed answer from de equipment. Is not what i wanted but it works.

I'm not sure that this fulfils your need,
but you can use the savewave() function to generate a .wav file,
then use any player to generate the output signal while recording with another 
application.

[Scilab-users] Simultaneous record and play sound with scilab

[Pablo Fonovich]

Hi:

I have to test some audio equipment i've built, and i wanted to know if its 
possible to play a sound and record an input simultaneously with scilab. There 
is a portaudio toolbox, but is a bit old and i could not manage to get it 
working.

The idea is to generate some sinusoidal signals and play them throuh a pro 
audio card. That signal is going to be fed to my audio equipment under test and 
the response of it should be recorded by scilab. So i do not need to play what 
i'm recording; from scilab's point of view, they are two independent signals.

Thanks in advance

Re: [Scilab-users] Converting UT to Standard Time

[Pablo Fonovich]

Hi:
You may also define a vector with any label regardless your data, and the data 
of a particular point could be visually interpolated by the reader with a grid, 
just like excell does... I'm not sure if i'm clear enough... i'll send you an 
example

time = [63602,63602.05,63602.09,63603.5,63604,63606]
values = [1,2,3,4,5,7]

function convertedtime = timestring(UT) //converts UT
h=int(UT/3600);
UT=UT-h*3600;
m=int(UT/60);
UT=UT-m*60;
if UT < 10 then
convertedtime = string(h) + ":" + string(m) + ":0" + string(UT);
else
convertedtime = string(h) + ":" + string(m) + ":" +string(UT);
end
endfunction

timeTics=time(1):0.8:time($)

newtime = timestring(timeTics);
plot(time,values);
a=gca();
ticks = a.x_ticks
ticks.labels=newtime
ticks.locations=timeTics
a.x_ticks=ticks

Of course, the label does not represent actual data you read from a file or 
something, they would just be text labels to let you read the plot... with this 
approach you can define the distance between each tic easily

if you use time = [63602,63602.5,63603,63603.5,63604,63606] the plot's tics 
become clearer...

The second question is how near this tics are supposed to be in the worst case? 
for example, if your time conssists of values sepparated about 0.05, you could 
create a new vector containing the positions of the tics, that exclude too near 
values... I mean:

time = [63602,63602.05,63602.09,63603.5,63604,63606]
values = [1,2,3,4,5,7]

newtime = timestring(timeTics);
plot(time,values);

Re: [Scilab-users] integrals

[Pablo Fonovich]

Hi:
As tim stated before, scilab does numerical calculation of integrals, very 
usefull for ingeneering problems for example... but does not provide any 
function for symbolic calculation of integrals. If you really need symbolic 
computation of an integral, i would recommend you using maxima, or wxmaxima if 
you are a begginner... There is also a toolbox for doing symbolic calculation 
trhough maxima in scilab called "scimax", you could try it if you want to do 
everything in scilab, but i think is a bit outdated.

May i ask you why you need to do a symbolic calculation?

void1 = []
options = 
tlist(["scsopt","3D","Background","Link","ID","Cmap"],list(%t,33),[8,1],[1,5],list([5,1],[4,1]),[0.8,0.8,0.8])
void2 = []
void3 = []
doc = list()
1 CLOCK_f
2 RAND_f
3 SUMMATION

6 DEMUX
7 GAIN_f
8 SUM_f
9 SPLIT_f
10SUPER_f
11SUPER_f
12SUM_f
13CSCOPE
 
i would like to be able to generate the same diagram with that information by 
myself, to open it with a custom application... is the scs_m enough? is there 
any documentation from where to start?

Subject: Re: [Scilab-users] Limit command




Hi:
Limit IS a scimax function... i used your script and it worked with some 
modifications...

First of all, the scilab function "roots" need a variable type polinomial as 
argument... and the symbolic polynomial made by scimas is not this type of 
variable, so we need to use scimax's function "sym2poly"...
However, sym2poly needs an expanded polynomial as argument... so we first need 
to use "expand" on the polynomial we want to calculate the roots... So your 
final script should be:

z = %z;
Syms n z1;
z = z1
X =z *(3*z -(5/6) ) /((z -(1/4) )*(z -(1/3) ))
X1 = expand(denom (X));
X1=sym2poly(X1,'z1');
zp = roots(X1);
X1 = z1 *(3* z1 -(5/6) ) /(( z1 -(1/4) )*(z1 -(1/3) ))
F1 = X1 *( z1 ^(n -1) )*(z1 -zp (1) );
F2 = X1 *( z1 ^(n -1) )*(z1 -zp (2) );
h1 = limit (F1 ,z1 ,zp (1) );
disp (h1 , ' h1 [ n]= ' )
h2 = limit (F2 ,z1 ,zp (2) );
disp (h2 , ' h2 [ n]= ' )
h = h1+h2;
disp (h, ' h [ n]= ' )

Now, the differences in your script and mine could be because the version of 
scilab or scimax in which the author programmed that script may not be the 
lasts ones...

I would recommend you to define polynomials with the native scilab functions... 
scilab has enough functions for polynomials... the script would be:

X =poly([0 1],'z','coeff')*poly([-5/6 3],'z','coeff') /(poly([-1/4 
1],'z','coeff')*poly([-1/3 1],'z','coeff') )
X1 = denom (X);
zp = roots(X1);
X1 = z1 *(3* z1 -(5/6) ) /(( z1 -(1/4) )*(z1 -(1/3) ))
F1 = X1 *( z1 ^(n -1) )*(z1 -zp (1) );
F2 = X1 *( z1 ^(n -1) )*(z1 -zp (2) );
h1 = limit (F1 ,z1 ,zp (1) );
disp (h1 , ' h1 [ n]= ' )
h2 = limit (F2 ,z1 ,zp (2) );
disp (h2 , ' h2 [ n]= ' )
h = h1+h2;
disp (h, ' h [ n]= ' )

and the only function from scimax is the "limit" command

X1 = expand(denom (X));
X1=sym2poly(X1,'z1');
zp = roots(X1);
X1 = z1 *(3* z1 -(5/6) ) /(( z1 -(1/4) )*(z1 -(1/3) ))
F1 = X1 *( z1 ^(n -1) )*(z1 -zp (1) );
F2 = X1 *( z1 ^(n -1) )*(z1 -zp (2) );
h1 = limit (F1 ,z1 ,zp (1) );
disp (h1 , ' h1 [ n]= ' )
h2 = limit (F2 ,z1 ,zp (2) );
disp (h2 , ' h2 [ n]= ' )
h = h1+h2;
disp (h, ' h [ n]= ' )

Now, the differences in your script and mine could be because the version of 
scilab or scimax in which the author programmed that script may not be the 
lasts ones...

I would recommend you to define polynomials with the native scilab functions... 
scilab has enough functions for polynomials... the script would be:

X =poly([0 1],'z','coeff')*poly([-5/6 3],'z','coeff') /(poly([-1/4 
1],'z','coeff')*poly([-1/3 1],'z','coeff') )
X1 = denom (X);
zp = roots(X1);
X1 = z1 *(3* z1 -(5/6) ) /(( z1 -(1/4) )*(z1 -(1/3) ))
F1 = X1 *( z1 ^(n -1) )*(z1 -zp (1) );
F2 = X1 *( z1 ^(n -1) )*(z1 -zp (2) );
h1 = limit (F1 ,z1 ,zp (1) );
disp (h1 , ' h1 [ n]= ' )
h2 = limit (F2 ,z1 ,zp (2) );
disp (h2 , ' h2 [ n]= ' )
h = h1+h2;
disp (h, ' h [ n]= ' )

and the only function from scimax is the "limit" command

Re: [Scilab-users] Limit command

[Pablo Fonovich]

Hi:

i looked in the scilab help with scimax toolbox loaded, and it finds limit 
function! its a scimax function...
Can you send me what errors appears in the console when you try to execute that 
script? I'm having some troubles with the scilab function roots...

Im using scilab 5.5.2 however...

Hi:
i think i finally solved your problem
 use this script

Syms n z ;
x1 =(0.33) ^( n )
X1 = %sym_sum (7* x1 *( z ^( - n ) ) ,n ,0 , %inf )
X1=ev(X1,'simpsum=true')
x2 =(0.5) ^( n )
X2 = %sym_sum (6* x2 *( z ^( - n ) ) ,n ,0 , %inf )
X2=ev(X2,'simpsum=true')
X = X1 - X2

i just added the ev instruction after calculating X1 and X2 to simplify the 
sum...

the result is

 X  =
 
 7.06.0
  - - ---
   33  1
  1 - -   1 - ---
  100 z   2 z

that is correct!

Hey: Another thing, in maxima sometimes when the output is a summation like the 
one you showed, you can say maxima to calculate it with the command 
"simpsum=true"... i don't know if there is a similar command for scimax, but 
there should be... perhaps if you search in scimax's help

Re: [Scilab-users] Symbolic computation in Scilab

[Pablo Fonovich]

Hi:
First of all... scilab latest stable version is 5.5.2, not 5.3... i asked this 
to you cause i wasn't able to install scimax in scilab 5.5.2 so i could not try 
your script... 

Then, i think that the output you are getting is just the summation... let's 
take a look to the output of x1:

First you have the 7 scale factor, then, the "=" , "/", and "\" form the symbol 
of a summation, from n=0 to %inf... then... inside of it you have 
0.33^n/(z^n)... so what scilab did was writing the summation in a symbolic 
way... It does that cause that summation is not always convergent i think.. 
Perhaps you can see it if we write tha same like this:

 %inf
     n
\   0.33
 7   >- n
/  z
    
 n = 0



If you could somhow specify that |z|>0.33 before doing the summation, but i 
don't know how to do it on scimax... If you try with maxima alone the result is 
ok.. 

If i can install scimax in scilab 5.5.2 i will try to solve this problem you 
are having

Hi:
I assume that you wanted to calculate the z-transfor of the difference of 7*x1 
and 6*x2... And for the limits of your sumation, i also assume your sequence is 
causal...
In theory, if im not making a mistake, X1(z) should be 1/(1-0.33*z^(-1)) and 
X2(z)=1/(1-0.5*z^(-1))...

If this is right, the answer should be the difference between them, scaled by 7 
and 6 respectively...

If i do the calculations with maxima i get the expected result...

However, as i think i told you before, maxima asks for some convergence 
conditions...

For example, when i try to do the first summation it ask if |z|-0.33 is 
positive, negative or zero... this is like giving the ROC of the z transfor, 
that in this case is |z|>0.33 so you have to answer "p" for positive...

Hi:
Im courious about one thing... if i may ask, what are you going to do with the 
z-transform? Is the z-transfor the result of your excersise, or you want it to 
do some other calculation after that?
Could you give me some more information about the problem you wan't to solve?

I would also tell your teacher to let you use Maxima alone for symbolic... 
SciMax toolbox is a bit old, and i'm not sure if it's fully compatible with the 
newer versions of scilab and maxima.

I totally agree with Tim's answer

Re: [Scilab-users] Symbolic computation in Scilab

[Pablo Fonovich]

Hi:
As far as i know, scilab does not have a symbolic function for an infinite 
summation...
Scilab is mainly intended for numeric calculation... so that functions are not 
yet implemented (perhaps in future versions).

If you want to do a symbolic calculation of the z-transfor you mentioned, and 
you want free software, i would use maxima... It's a powerfull symbolic 
software...

In maxima you could simply do

"sum(0.5^n*z^(-n), n, 1, inf), simpsum;"

then, you will have to input some conditions that you can see from the ROC of 
the z-transform... In this case maxima will ask:

"Is "2*abs(z)-1" positive, negative or zero?"

And i assume it's possitive given the function you want to transform... then 
you type 

"p"

and you will get the answer...

If someone knows a toolbox for scilab to do this... please tell us!

I hope this is usefull for you

Re: [Scilab-users] compatibility Atoms scilab 5.6 / Ubuntu14.04

[Pablo Fonovich]

Hi... i assume you reffer to the yasp version? i mean... scilab 6.0 current 
development?
i think it tries to look for scilab 6.0 repossitory for atoms, but it is not 
yet available... so i think you coud just use:

atomsRepositoryAdd("http://atoms.scilab.org/5.5";) and use the previous 
repository... when version 6.0 stable cames out, i think the 6.0 repository 
will be available...

The problem of this is that i cant remove 6.0 repo with 
atomsRepositoryDel("http://atoms.scilab.org/6.0 official")... and this brings 
trouble... 
perhaps you should just wait till this is solved in the new version

Subject: [Scilab-users] compatibility  Atoms scilab 5.6 / Ubuntu14.04





Hello

I have recently installed scilab 5.6 on ubuntu 14.04 but I get the following 
message with Atoms:

No ATOMS module is available. Please, check your Internet connection or make 
sure that your OS is compatible with ATOMS.

is there anyone who has run Atoms from scilab 5.6 on ubuntu 14.04?

thank you in advance for the feedback

Pascal

Re: [Scilab-users] scilab doesn't work after splash screen

[Pablo Fonovich]

Hey: Try uninstalling it once again... Then remove the folder:

 "C:/Users/YourUserName/AppData/Roaming/scilab-5.5.0" 

Replacing YourUserName with whatever your user is called... In my case it would 
be

C:/Users/Pablo/AppData/Roaming/scilab-5.5.0

Once you have uninstalled it... try reinstalling...

In fact... I would delete every folder called scilab before reinstalling, or do 
a clean remove with some application, ive heard of them but never used it.

Hello,I haven’t used scilab for a couple of months  and then Yesterday I opened 
it again for a university project. The problem is that scilab doesn’t work 
anymore, I already try to uninstall and reinstall it(version 5.5.0), I even 
tried to install 5.4.1 but the same problem appears. Version 6.0 doesn’t even 
start. I attach a screenshot, although I’m not fast  enough to catch the whole

Re: [Scilab-users] Fwd: Error installing HART toolbox in ubuntu14.04 LTS

[Pablo Fonovich]

Hi:I think you need to install portaudio before trying to install hart...Have 
you got synaptic package manager isntalled? you can look portaudio trhough 
synaptic and install it...If you don't have synaptic, perhaps you could try 
with:"aptitude search portaudio"and a list of packages containing portaudio 
should appear... then use "sudo apt-get install package"whith package i mean 
the realname of the portaudio listed by aptitude search... In a few hours i 
will have acces to an ubuntu pc and i would be able to tell you the exact 
commands..Once you've installed portaudio, you should be able to install HART.

I will try to include the libraries, and if i can't i will grab the functions

My expected target are dsPICs or microproccessors without operative system.

Re: [Scilab-users] Xcos code generation, compiling with eclipse for standalone usage

[Pablo Fonovich]

Thanks for your answer.

So, if i link the libraries by mysefl (like -L/usr/share/scilab/lib -llibrary) 
in the compiler, isn't possible to use as standalone anyways? If i can do that, 
what libraries should i link? If i can't, why is the standalone.c generated?

The errors i get is that cstblk4_m, selector_m, and counter are not defined, 
and i guess there are defined in a library, but i don't know in which

Other question... is there a code generator like equalis for dspic or embeedes 
systems, but opne-source? Equalis is far away my budget...

Subject: Re: [Scilab-users] ATOMS problem

Back again with the source of the trouble!
I thought I had cleaned every remnants of Scilab before reinstalling it. Then I 
was baffled by the fact that the new install "remembered" to load Plotlib 
Toolbox 0.45. So some old Scilab history file was still left somewhere. I 
looked in ProgramData but there is no Scilab folder there (where any Scilab 
data should be IMHO!). So I did a search and after a rather long time the 
hidden data was found in C:/Users/Rene/AppData/Roaming/scilab-5.5.0. 
Once it was removed a fresh install of Scilab cleared all problems.
Sorry for wasting your time, Pablo. 
I had completely forgot that some programs use that AppData folder rather than 
the more standard ProgramData. 
I'll looked into the folder I removed to see what I did to cause ATOMS to cease 
functioning in such a bad way.
A lesson however to anyone "haunted" by (bad) actions they did in the past: 
Scilab never forgets!
It is still surprising that Scilab uninstall does not wipe out its entry in 
AppData!
Thank you and sorry again for your trouble.
René.

Oddly it came with an empty graphic window. Perhaps uninstall Scilab didn't 
clean enough Scilab remants of previous disastrous sessions. I didn't dare do 
"exit", rather I clicked the option "x" to get out.
Next I'll wipe out all traces of Scilab and reinstall it again.
But meanwhile please find attached the atoms directory you requested in Word

Thanks for your reply, Pablo.
No I didn't change anything in my copy of Scilab. 
The last time I used actively ATOMS was to reload a corrected Matlab-like 
plotting library which unexpectedly had ceased to be compatible with the 
graphic module which comes with Scilab. As that compatibility was vital to my 
projects I reported it and it was soon corrected. So ATOMS was well behaved 
that last time I had to use it.
This week-end I just wanted to add maybe an image processor and was only trying 
to find what was available when I noticed that ATOMS didn't work anymore.
Yes I tried what you say, even directly inserting one of the examples from Help 
concerning the atoms package to be on the safe side. Scilab reported that the 
atoms package was not available and then a catastrophic error occurred. 
Unfortunately I failed to copy the error message in time. When I tried to exit 
Scilab instead relaunched itself into a loop repeating that last exit command. 
I could only terminate it with the Task Manager by ending the tasks faster than 
they were added to the list of running ones! Not easy winning that race...
Given your second e-mail I'll try to reinstall Scilab again and report back to 
you not trying any new trick: chat échaudé craint l'eau froide!
I fear that it might be related to a recent loadful of Microsoft automatic 
updates to my copy of Windows 7... 
Thanks again and greetings from Sydney where Spring is back!
René.

I uninstalled and reinstalled Scilab 5.5.0 to no avail. I even tried again as 
suggested on the web by installing it directly in C:\ but with the same error.
I tried some of the atomsXXX functions and got the message that package "atoms" 
was not available!
What is going on? I used ATOMS a lot in the past few years by just clicking its 
icon in the tool bar and without any problem.
(My PC is a HP ProBook 4730s under Windows 7. --- WIN32)
Thanks for any help!

Re: [Scilab-users] ATOMS problem

[Pablo Fonovich]

Hi: the problem is when you try to open the atmos gui? have you tried 
installing an atom's module by commands?
for example try:
   atomsInstall('guimaker')
or any other package you are interested in... If it works i think the problem 
is in your atoms gui.

As atoms used to work before... you may also try to restore your previous 
configuration with:
   atomsRestoreConfig()

Have u modified anything to scilab lately?

I uninstalled and reinstalled Scilab 5.5.0 to no avail. I even tried again as 
suggested on the web by installing it directly in C:\ but with the same error.
I tried some of the atomsXXX functions and got the message that package "atoms" 
was not available!
What is going on? I used ATOMS a lot in the past few years by just clicking its 
icon in the tool bar and without any problem.
(My PC is a HP ProBook 4730s under Windows 7. --- WIN32)
Thanks for any help!

[Scilab-users] Xcos code generation, compiling with eclipse for standalone usage

[Pablo Fonovich]

Hi: I would like to know if its possible to compile the code generated with 
xcos with eclipse (or other open-source ide) into an aplication for usage 
outside of scilab. I've been trying but im not able to do so.
If it's possible, is there any tutorial or something?
What i really want to do is to use the code generated as a function of another 
program.
