calling matlab dll from c

hi,

i am in need of calling matlab from with in C program for calculating a prt of the output. This has to be fed to the next stage. how can i invoke matlab from within C environment to do this? is it possible similar to running some dos comands within C? if not is it possible to do cluster computing with matlab(running a program on several comp. by splitting them into independent modules)... if so how to do it?.. and i know abt the distributed computing toolbox that has been issued by mathworks just now... which was not avaibale in the m14sp1 release...

i need to call matlab from C and not the other way! thou, thanks for the links. was useful. i need it anyway.

I think the links show examples that call matlab function from/in C. Pls correct me if I'm wrong. Thanks.

Using C Math Library

To add support of MATLAB C Math Library follow these instructions:
1- Add following line at the end of stdafx.h

#include <matlab.h>

matlab.h is interface of MATLAB APIs. Add directory of MATLAB interface files (*.h) to Visual Studio (Tools -> Options -> Directories). For example: x:\matlab\extern\include where x is drive letter of matlab path.

2- Add desired libraries to your project (In this example, libmat.lib, libmx.lib, libmatlbmx.lib and libmatlb.lib)

3- Compile your project!
Sample Program

#include "stdafx.h"

int main(int argc, char* argv[])
{
double dblArray[]={1, 2, 3, 4, 5, 6, 7, 8, 9};

mxArray *A, *B; A=mxCreateDoubleMatrix(3, 3, mxREAL);

//copy array to matrix A

memcpy(mxGetPr(A), dblArray, 9 * sizeof(double));

A=mlfMTimes(A, A); //A=A.^2;

mlfPrintMatrix(A); //Creating Magic Matrix

B=mlfMagic(mlfScalar(3)); //Magic matrix of order 3 

mlfPrintMatrix(B);

mxDestroyArray(A);

mxDestroyArray(B);

return 0; }

Re: calling matlab in C... possible?

Yes, of course you can.
The most recommended method connecting C and matlab is MBuilder.
You can find help in matlab soft.

Good luck!

Re: calling matlab in C... possible?

yes it is possible,
you can use a generic perl script also for that.

There is a demo program given in the link above:

myprog.c

But it's a demo of calling a C function from MATLAB

If I'm not mistaken, arunmit168 is looking for a solution of calling matlab (function) from C program
