Re: [Scilab-users] The numderivative function
Hello Hermes,
If you're using Scilab 6.0.0 the function numderivative is in the
differential_equations module so you should use:
exec(SCI+"\modules\differential_equations\macros\numderivative.sci", -1);
If you want your script to be compatible with both versions you can add:
v = getversion("scilab");
if v(1)<6 then
exec(SCI+"\modules\optimization\macros\numderivative.sci", -1);
else
exec(SCI+"\modules\differential_equations\macros\numderivative.sci", -1);
end
Best regards,
Paul

Hi,
When I execute the command:

I get the following Scilab alert:
exec('C:\Draghilev''sMethod_4.sce', -1)

the command is inserted in the script before calling the fumciont ode.
it is right?

[Scilab-users] Scilab 5.5.2 on macOS High Sierra
Hello Mac users, As Scilab 5.5.2 requires a Java 1.5 install, we need to make it think it has one. Here are steps to run Scilab 5.5.2 on High Sierra: * open a terminal (found in Applications -> Utilities -> Terminal) * note the path returned by: * /usr/libexec/java_home * in my case it returns /Library/Java/JavaVirtualMachines/jdk1.8.0_102.jdk/Contents/Home so in the following commands, replace it with your path. Run the following commands (you'll need sudo rights): * sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.8.0_102.jdk/ /System/Library/Frameworks/JavaVM.framework/Versions/1.5 # Make Java 1.5 point to our install * sudo mkdir -p /bundle/Libraries * sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.8.0_102.jdk/Contents/Home/jre/lib/server/libjvm.dylib /bundle/Libraries/libserver.dylib # Make the requested libserver.dylib file point to our libjvm.dylib * if you get 'Operation not permitted' errors then please consult http://osxdaily.com/2015/10/05/disable-rootless-system-integrity-protection-mac-os-x to bypass macOS protections * at Scilab startup, click on Try Anyway when asked about the macOS version * if you're asked for Java6, follow the steps described at http://www.scilab.org/en/download/latest Regarding Scilab 6, it is recommended to wait for the next Scilab release which simplifies the launch on High Sierra. Otherwise you may refer to http://bugzilla.scilab.org/show_bug.cgi?id=15307 for a workaround.

Re: [Scilab-users] Xcos Coselica blocks - Error while running - C compiller
Hello Gnu, To run Xcos demos containing Modelica (/Coselica) blocks, you need a C compiler, as your message title suggests. Please refer to the compilers page (https://help.scilab.org/docs/6.0.0/en_US/supported_compilers.html) for that. Alternatively, you may try with Scilab 5.5.2 and even report a bug (http://bugzilla.scilab.org) should you encounter unexpected behavior.

A block label in Xcos will be deleted, if it is part of a subsystem (inside a superblock) and altered outside of Xcos.

When I alter the content of that field, or even pull the scs_m data from Xcos and try to reopen / reload it using the xcos(scs_m) command, all labels inside of superblocks are deleted.

Re: [Scilab-users] Optim use and 'err' flag
To complete my previous answer, the error arose from the built-in line search algorithm (err>10 means different flavors of it failing). In your case, it is pointing to a "too small deltaT", so yes it looks like your algorithm is converging but it has trouble finishing. You can get more info by using "imp=3" in your call to optim (as documented). If you are using a nightly build then use "iprint=3" (the online doc hasn't been updated yet).

Re: [Scilab-users] API Error
Hello Shamika,
Are you sure that 'c' is a mlist? When I try you code with
-->c=hypermat([2 3 2 2],1:24); callOct(c);
with a dummy callOct, I get an early error in getListItemNumber:
"API error: in getListItemNumber: Invalid argument type, list expected"
"This variable is not a list"
Now wen I try with
-->c=list(1,2,3); callOct(c);
I don't get an error.
Hope this helps,
Paul

Re: [Scilab-users] Cannot start Xcos
Stefan,
You are launching Xcos properly, but this number of toolboxes looks
suspicious to me, one of them may be interferring.
Can you please disable their autoload and try to launch Xcos? If it
works, you may want to load them one by one until you can't relaunch
Xcos ; that way we'll know which one is causing the trouble.
Thank you, best regards,

Hi Pierre,
What you want to do is check your environment at context evaluation,
so simply write a "pause;" at the start of the context and when you
press Play
you will be prompted to resume in the Scilab console.
You can then write "-->who()" or "-->who('get')" to list all existing
variables.
Note that you can safely overwrite these variables because when you
leave your context the modifications will be lost (their scope is
limited to the context).

Hello Paul,
Thanks you for your quit response
It confirms that « tf » is a reserved word in Xcos context, and must
be used with caution.
In fact, I shall drive in September a student in Master2 on a subject
concerning turbines simulation, and I inherit a program done with Xcos
where condition « if ~exists(« foo ») foo=xx » is systematically
used, and I see a big number of Xcos blocks and hundreds of variables.
This is correctly done because all variables are not necessary
transmitted when launching Xcos. Part of them are redefined, part of
them are values by default, which explains this program structure done
by a student a few year ago.
So, has to control that, my main question was to know where I could
finf a list of reserved words or variables in xcos.
We have together seen that « tf » was one of them, which also define
the « Final Integration Time »
I had a look on the Help in Scilab (describing a lot of thing », very
clearly, but nothing about « tf » for example.
For example, what are the others reserved keyword for the rest of
these variables, in the above table ?
A list would be welcome, or a reference to access this one.
Your sincerely,
Pierre

OBJET : Re: [Scilab-users] Xcos - Problem with tf variable name in a
superblock
Hello Pierre,
10 is indeed the "Final integration time" parameter in the
Simulation->Setup menu.
By using exists() (you might want to use isdef() [3] instead) you
don't override the existing parameters,
and in Scilab, functions can see the superior-scope variables (here,
'tf').
So just write "tmf=3; tf=2;" in your context and everything should run
fine.

Paul

Re: [Scilab-users] Error during Simulation
Hello Tarun, Could you please attach your diagram file instead of a screenshot of it? The error you are getting is the solver telling you that it could not converge. Indeed, there is a default limit of 500 steps for CVode. The fact that the solver did all of them (delta large enough between two steps) indicates that your system is either going back and forth or slowly converging. It must be one of your CLR blocks that return that error, since they are the only ones in your diagram with continuous states. Changing the solver (Simulation-Setup) or tuning the tolerances may help. Also, what version of Scilab are you using?

Re: [Scilab-users] Problems with To workspace and From workspace
Hi Michael,
When I run the simulation a second time, I still get the "Protected
variable name" and "Singularity in a block" (block _expression_)
errors.
The attached diagram does what I think you are trying to do (without
running the script).
That is, when the ramp block crosses zero, save the value of the
sine block in Scilab environment and plot it.
The CLKSOMV_f block is just there to give an initial impulse to
DOLLAR_f thanks to the added CLOCK_c block.
As Serge stated, the variables are "transferred" to the Scilab
environment at the end of the simulation, so there is no way of
saving a variable AND loading it mid-simulation in one diagram.
Hope this helps,
Regards,
Paul

Hello Paul,
thank
you for your answer.
I
had a look at the DOLLAR block. Its a kind of delay
block, but its not the right block for the task I have to
do, I think.
I
attached a simulation file, which shows the problem. This is
not the real simulation, because the real one is more
complex.
First
of all I load the .sce file. If I start the simulation, the
output shows the result with the initial value of C defined
in the .sce file and I get the error message Evaluation
problem: value not updated from context. Protected variable
name. Please choose another variable name.
After
I start the simulation a second time, the output graph shows
the correct result and the error message doesnt appear
again.
Is
there any possibility to write into my variable C at the
beginning of the simulation? Or is it possible to do this
task with the DOLLAR block like you thought?
Best
regards,
Michael

Hi Michael,
Indeed it looks like you can't overwrite a variable defined in
the context.
Have you tried replacing the "FROMWSB" block with a "DOLLAR"
block?
Then it would have the same data and activation inputs as the
"TOWS_c" block,
and you would not need to pre-define 'C' (just give it an
initial value in the block parameters).
Hope this helps,

Re: [Scilab-users] Problem running xcos in batch mode from Scilab
Hello Romain,
The difference is due to the solver type. Your diagram currently selects
the ODE solver Sundials/CVode - BDF - Newton.
xcos_simulate(scs_m, 4); detects two continuous states and
switches to a DAE solver (Sundials/IDA).
scicos_simulate(scs_m); only detects one continuous state and
keeps the ODE solver.
This must be due to a Modelica compilation difference between xcos and
scicos.
I don't know the equations of your model so I cannot assess which method
is correct.
Also, I noticed that the context variables (C, R, T, end_time) are not
present in the diagram, so what are you trying to change when you modify
the context? You might want ot use the END
http://help.scilab.org/docs/5.4.1/fr_FR/ENDBLK.html block to set the
end time.
Hope this helps,
Regards,
Paul

During the compilation, a WARNING is displayed to notify the solver switch. xcos_simulate(): WARNING: Diagram has been compiled for implicit solver switching to implicit Solver scicos_simualte(): no warning, so no switching. If the diagram contains continuous states, xcos and scicos are supposed to detect the problem type (ODE or DAE) and switch to the default one (Sundials/BDF-Newton for ODE and Sundials/IDA for DAE) if the Setup solver is not adapted.

Re: [Scilab-users] scilab-fortran issues
Hello Eduardo,
The call() primitive is not (yet?) suited for string matrices, because
there is a confusion about the size of it: right now, the gateway
detects the size of a scalar string, but when it is a matrix, each
element can have a proper size (buffer) and there is also the matrix
size itself.
To avoid this confusion, the gateway only allows scalar strings, so the
size of the argument actually represents its length (for instance,
ident=STR1 will be detected as having a 4x1 size).
This is documented in the help page
http://help.scilab.org/docs/5.4.1/en_US/call.html, the arguments can
be real matrices or [scalar] strings.
So my only suggestion at the moment is to pass ident as the
concatenation of its elements, and to split it (or iterate on its
length) in the Fortran routine. ident = STR1+STR2+STR3+...
Hope this helps, otherwise feel free to report a bug on
http://bugzilla.scilab.org/
Regards,
Paul

The first example on this http://lpsa.swarthmore.edu/Bode/BodeExamples.html page also shows a gap ( s = poly(0, s); bode(syslin(c, 100/(s+30))); ) On 12/13/2013 03:04 AM, Vijay Gopal wrote: Hi, I am a scilab user and I find it amazing about its capabilities.

Re: [Scilab-users] Scilab Xcos Datatips
Dear Alexander, You may zoom on your curve to place your datatip more accurately. There are five significant figures when you place a datatip, so if Y: 1.1 is displayed, then it was closer to 1.1 than to 1.005. Regards, Paul.

My Problem is, that i need more decimal places for the Y-Axis. The problem is only if the datatip is over 1. It would be most helpful if there is a possibility to show the position of de datatip in a way like this for example: Y: 1.05 or Y: 1.005 it only shows Y: 1.1 (not very) For a better understanding look at the attechment.

Re: [Scilab-users] Number of plots limited in Xcos scope?
Hi Florian, So you want an ouput that looks like a subplot http://help.scilab.org/docs/5.4.1/fr_FR/subplot.html? If it is the case, did you try using a CMSCOPE http://help.scilab.org/docs/5.4.1/fr_FR/CMSCOPE.html block? If this doesn't work, could you please provide us with your diagram?

Re: [Scilab-users] Matrix of characters conversion
Dear Paul,
How about manually editing your file to standardize the spacing between
the numbers?
For instance, using your editor's Find and Replace tool to replace two
spaceswith one space until you get only one space between each
number?
Hope this helps,
Have a good day,
Paul.

Dear All
How can I convert a matrix of characters into integers when the
separator has different number of spaces ?
The spaces come probably from a printf format such as :
printf(%10d\n,var)
I 'm currently using*_csvTextScan_* and I've some troubles/errors
with*_csvRead_* ...
_Example_:
! 36 12799 24678 17504 21558212801 24680
17508 21560 !
NB:
-I read first an ascii file
-I removed some specific lines directly in the matrix
-Then I'm trying to convert the matrix of characters into a matrix of
intergers
Thanks for any suggestion

Re: [Scilab-users] Solving linear problem in scilab using Karmarkar and Primal Affine Scaling Method
Hello Jennifer, Are you certain that our problems are worrectly written? For intstance, why is there a 2 alone in a line of the first problem ? And why do your right-hand side elements all have x (0x, 1x, 15x)? I cannot rewrite them but I can tell you that yes, karmarkar allows to solve such problems. Just have a look at its help page : http://help.scilab.org/docs/5.4.1/fr_FR/karmarkar.html Your first problem should look something like this: c = [1 -2 0 0 4]'; // Main problem Aeq = [1 0 -1 0 0 ; ? ? ? ? ? ; 1 -2 4 0 -4 ; ? 2 0 1 -4 ; ? 1 1 1 1]; // Equations beq = [0 ? 0 0 1]; // Right-hand side [xopt, fopt, exitflag, iter, yopt] = karmarkar(Aeq, beq, c) If the solution is not all positive (inequality constraint), add an inequality matrix A, like in the help page. Hope that helps, Paul.
