Re: [Scilab-users] example of library

2019-11-18 Thread Federico Miyara


Stéphane,

Thanks for your answer.

I'll try, as soon as I can, to see if I'm able to go into the GIT world, 
but it may take much more time than your second option.


So my next question is, how do I find the files to modify?

Should I download the source code?

And--this is embarrassing--I cannot track back what help page my own 
correction,


http://bugzilla.scilab.org/show_bug.cgi?id=16250

refers to, and as the bug is a very unspecific typo I cannot recall it.

Thank you very much for your patience!

Regards,

Federico Miyara

If all those things are too complicated for you, just give us (for 
example me or Samuel) the modified files and we will create the commit 
and you will be able to edit/update it directly on codereview.scilab.org

Samuel,

  * login on the CodeReview portal, with your usual (Bugzilla)
Scilab login and password:
https://codereview.scilab.org => Sign in, in the top right
  * Contribute to an existing commit, just through the web interface.

Creating new commits and managing them is (quite) more complicated 
(at least it was, for me).
But many contributions are possible directly with the web interface, 
without knowing GIT,

including editing files.


Would you please give me some extra hints?

I'm quite serious about starting to contribute corrections and 
improvements to some help pages, the only area where I feel confident 
that I can put my two cents for the time being (besides just 
detecting bugs).


I've been able to login, I arrive at this page:

https://codereview.scilab.org/#/q/status:open

There are many open subjects, of course none of them matches the bug 
I've filed earlier:


http://bugzilla.scilab.org/show_bug.cgi?id=16250

Anyway, I proceed and open the first one:

https://codereview.scilab.org/#/c/20723/

But now I'm completely at a loss. How do I locate the help page I 
want to edit from here?


Thanks in advance.

Federico Miyara

[Scilab-users] symbolic functions

2019-11-18 Thread Federico Miyara


Dear all,

I've found in a tutorial 
(http://ryanrossi.com/teaching/search/papers/scilabguide.pdf) reference 
to some symbolic functions such as addf or trianfml, and even official 
Scilab help pages seemingly for an earlier version 
(https://help.scilab.org/docs/5.5.2/en_US/trianfml.html), but they have 
been removed from version 6. Any idea why?


Regards,

Federico Miyara

Re: [Scilab-users] How to fix the round off error of "intg"

2019-11-18 Thread fujimoto2005
Dear Samuel
Thank you for your reply.

Inside the function f(x),I added "disp" to display the value of x and error
flag "ierr" after "intg" line .

The "fsolve" and "numderivative" called f many times for many x around the
correct solution x, and the values of x and ierr were displayed for many
calls.
I couldn't find regularity because ierr = 2 occurs for x very close to x
with ierr = 0. I couldn't find the cause of the rounding error.
I couldn't proceed further since the inside of "intg" could not be
monitored.

However, when "ierr" is output, it turns out that the code did not stop even
if the rounding error occurs. As a result, fsolve could find the correct x.

I adopted this ad-hoc solution. Since the inside of g (x, z) have not been
improved so that rounding errors do not occur reliably, similar problems may
occur in the future, but I decided to satisfy this ad-hoc solution.

Best regards,
Masahiro Fujimoto

Re: [Scilab-users] using transparency in Scilab

Dear Scilab developers,

it seems that the topic of using transparency in Scilab pops up now 
and then.


So wouldn't it be useful to implement transparency once and for all 
into Scilab instead of using work-arounds?
Of course yes. But prepare to find a JoGL specialist knowing Scilab 
internals (kind of Unicorn...)


Just a humble question :-)

Best regards,
Philipp
