about code compatibility...

i have a matlab code that also includes c file...its a very old code and is been tested in matlab 6.5...what modifications must be made in order to run the code... and also i wanna know how c function should be called from matlab....thank u in advance..

Please clarify what kind of C file this is - is it a MEX-function (look for a function called mexFunction defined in the file), or a generic C file that needs to be compiled into a shared library.

Hello,

To call C functions from MATLAB, we typically use MEX files. If your MATLAB code also calls C functions via MEX files, you may need to recompile them using the current MATLAB version. The MEX API could have changed, so you might need to make adjustments to your C code. Use the 'mex' command in MATLAB to compile the C code into a MEX file.

mex myFunction.c

Once compiled, you can call the MEX function just like any other MATLAB function. Also, you may need to configure MATLAB to use a specific C compiler. Use the following command to select and configure the compiler.

mex -setup

Hope it helps!
