My knowledge of Matlab is freezed as of 2017, when I abandoned Matlab 
and embraced Scilab, so might be some of my comments are outdated


It is free, open source software

No licenses that eventually expire

Strings are better handled. In Matlab you can check for equality only if 
their lengths are the same since they are just vectors of codes. In 
Scilab a string is a true type for supporting many operations in a more 
intuitive way.


Variable names support extended characters

You can extract components from the result of any function: y = fft(x)(1:5)

The same applies to any field of structure

It is mostly compatible with Matlab and you can automatically convert 
Matlab scripts to Scilab scripts, which allows to reuse Matlab code (it 
is not perfect and manual correction is needed)


Insanely powerful control of graphics.

Impressive community to help with any doubts.

Federico Miyara

[Stéphane Mottelet]

Chat GPT answer (with a few inexact facts removed):

Scilab and MATLAB are both powerful mathematical computing environments, 
but they have some key differences that may make one more suitable for a 
particular use case than the other. Here are a few potential advantages 
of Scilab over MATLAB:


 *

   Open-source: Scilab is open-source software, which means that it is
   free to download and use, and the source code is available for users
   to modify and distribute. MATLAB, on the other hand, is proprietary
   software, and requires a license to use.

 *

   Cross-platform compatibility: Scilab is available for Windows,
   macOS, and Linux, which makes it more accessible for users on
   different operating systems.

 *

   Interoperability: Scilab can call functions from other programming
   languages, such as C and Fortran, which can be useful for
   interfacing with existing code.

 *

   Cost: As mentioned before, Scilab is open source, which means you
   can use it without any license cost unlike Matlab which require
   purchasing a license to use it.

It is also worth noting that Scilab and MATLAB are both based on similar 
ideas and share a similar syntax, so users familiar with one system 
should be able to pick up the other relatively easily.


In general, Scilab might be a good option for users who are looking for 
a free or low-cost alternative to MATLAB, or for those who need to 
interface with existing code written in other languages. However, in 
terms of the functionality, Matlab is often considered as more mature 
and have a wider range of toolboxes for advanced functionality.


So the choice between Scilab and MATLAB would depend on the specific 
needs and constraints of the user.

 Hello, guys. I have a problem with FROMWSB block. I simulate a simple model 
which use a workspace parameter (V.time and V.values) and draw a simple 
graph.When i use scicosim function i want to change a parameters of FROMWSB 
block (new V.time and V.values) and continue simulation. But i don't know how 
to change a parameters of this block. Is it possible? Please, I need your help. 
Thank you.

Hi,

The start-up file (I presume scilab.ini under Windows) resides in the 
directory whose name is effectively given by SCIHOME.
But it does not exist by default: you have to create it.
That's probably why you cannot find it.

Hi.

1) The cost of Scilab.
2) Scilab allow working in Windows and GNU/Linux simultaneously (for me 
it is the biggest advantage). If alphabet of your language is larger 
than ASCII, then you will appreciate it. Matlab is cross-platform but 
codepage is its weak point.

Hi everyone

Is there a way to clear the crrent line in th console? In most 
consoloes, [ESC] does that, but not in scilab




Ctrl+U to clear from the beginning of the line to the cursor.
Ctrl+E then Ctrl+U to clear the whole line (Ctrl+E moves to the end of 
line and Ctrl+A to the beginning).

It's the same in tcsh, bash and many others (comes from emacs I think).

Hello again

De la part de Renzo Zini
Envoyé : mercredi 24 avril 2013 15:58

 with the Windows calculator the result is

 915106577189,6470588235294118

another point is: does the Windows calculator compute the right value?

You can have a greater precision by performing two divisions:

(a + b)/c = a/c + b/c

each having no underflow.

then :
55568095557812224 = 55568095557812200 + 24

--155568095557812200/17
 ans  =
 
915106577188.

--24/17
 ans  =
 
1.4117647058823530326066

so we can guess that
55568095557812224/17 = 915106577189.4117647...

so the Windows calculator gives a result, but it is false at the first
decimal...

Now: do you really need to have a precision of more than 16 digits?

This might be the case, especially if the error propagates.

In my field, I'm usually happy with 4 digits ;-)

[Zeyu Liu]

actually, with bc program in Linux, I get

915106577189 * 17 = 155568095557812213

and obvious this precise. and with scilab, I get

--format (25);

--11 / 17
 ans  =

0.6470588235294117973595

so the windows calculator is correct.

[Renzo Zini]

Yesterday I have seen a strange behaviour of a simple algorithm I wrote.
After some investigation over that, I write this operation on scilab console
(after this format was changed with this instruction  -format(25) )

-155568095557812224/17
 ans  =

915106577190.

and I know this is wrong because 17 does not divide that number

with the Windows calculator the result is

915106577189,6470588235294118

This thing seem so incredible to me, that I ask:
Why scilab have made this error?
It's my fault? Or it is a bug
how I can fix it?
