Running standalone scilab application under windows

[velk...@yahoo.com]

Hello,
I am new to Scilab and don't seem to be able to find enough relevant
info on the topic.

How can I compile Scilab application program to run standalone in
Windows ?
In other words, is there a way to make an .exe output from Scilab ?

Thanks.

Hi,

there is many ways to exec Scilab in standalone mode.
Two of them are :
1-Run Scilab in batchmode like this "C:\Program Files\scilab-4.1.1\bin
\scilex" -nw -f MonScript.sce
2-Have a look at this directory : "scilab-4.1.1\examples\callsci
\callsciC++" to learn HowTo use Scilab embedded in an C++ application.

hope this helps

What I have done, is to have Excel Visual Basic for Applications (VBA)
macro
call a process/program which is some program written in Visual C and
compiled into windows .exe,
let me call it myProgram.exe.
Than the process executes some math code inside myProgram.exe and
returns automatically to Excel.

What I need to do now is, instead of Visual C .exe, I have to do the
same thing but with code written in Scilab using some Scilab math
functions, and call
myProgram.sci.

I have the hardest part - process calling - figured out.
Under windows, in the VBA macro, I simply have a line such as
some_return_variable = ExecCmd ("myProgram.exe")
which causes the myProgram.exe to execute.

I guess, I do not understand if *.sci or *.sce can execute without
Scilab.
1) Does Scilab have to be started first to execute these files ?

2) Could I do simply ExecCmd ("myProgram.sci") same way as I did
before with myProgram.exe ?

My problem is that this application will be run on a PC without
Scilab, so I can not have the program start scilex
because it will not be there. Even if the user had Scilab installed, I
would not want Scilab to pop up either.

Thanks for any suggestions,
velkypivo

Another option would be using R/Scilab (D)COM Server available from
http://rcom.univie.ac.at/

Using this software, your application will have access to Scilab in form
of a COM object. The Scilab window itself is not visible.

Using R/Scilab (D)COM Server, you will have to instantiate the COM
component and initialize the component. This is similar to starting
Scilab---just without of the windows...

You will need Scilab to be installed on the computer in order to use the
component from R/Scilab (D)COM Server, but you can do this silently for
the user when installing your own application.

This is how the COM component works. No GUI, no windows just plain
Scilab backend functionality.

Ideally, I think Velkypivo wanted to be able to write a program in
Scilab and have people run it who do not have Scilab installed.
Thomas' method might be the closest he can get to that, but I have a
different idea, and was wondering if it's possible.

Does scilab have any feature where one can easily convert Scilab code
into Fortran/C/C++ code? I imagine that not all functionality would
be supported, but it would still be a lot easier to write programs,
and if one could easily switch to a compiled language than re-
compiling the code might allow other users to run the program.

Possible/impossible/wrong/thoughts?

short answer: NO.

There is an ancient and never finished, currently broken attempt of
Fortran translator currently built in, and there are rumors that a
decent scilab->C translator is planned for scilab 5.

How about using Scilab's DLL libraries ? I think, calling Scilab DLL
from VB would be easier.
Are Scilab DLLs ready to be called from C or VB ?
Is there a list of these DLLs ?

Thanks,
