Problem with C codes embeded in Matlab

I have a Matlab file contain a thread 'mex -O SegSegForces.c'. Since there is a file with extension c so I wonder what should I do if I want to run this program? I have MicroSoft Visual Studio installed but I don't know whether this can help with the c program?

I suggest reading the documentation concerning the command MEX:

docsearch mex

If the C-function has been compiled by MEX, it can be called exactly as an M-function.

It appears that SegSegForces.c is a MEX-function. For the compilation command "mex -O SegSegForces.c" to work, you must first setup a MEX compiler using the command:

mex -setup

Then, on running the mex compilation command, you should see a binary called SegSegForces.mexw32 (or .mexw64 if you're on 64-bit Windows) generated. You can now call this function 'SegSegForces' like any other MATLAB function.

Thanks. But which compiler should I used? I have seen Lcc-win32 C (and others) in the list of options when I type mex -setup in the command window. The user manual of this set of program has mentioned gcc 3.3. Should I download and install it? My OS is Win XP.

You can try LCC, which is shipped with Matlab 32bit versions. The Visual Studio compiler are more powerful, therefore I suggest it, if you have installed it already. GCC is for Linux platforms.
