wrong mailing list, you might want to try the matlab news group. but,
to answer your question, mex files all have the same syntax:
void mexFunction(
int nlhs, /* number of expected outputs */
mxArray *plhs[], /* mxArray pointer array returning
outputs */
int nrhs, /* number of inputs */
const mxArray *prhs[] /* mxArray pointer array for
inputs */
)
no matter what type of array you pass. you then need to get the data
pointer, the sizes for the arrays, etc... like:
mydata = mxGetPr(prhs[0]);
dims=mxGetDimensions(prhs[0]);
ndims=mxGetNumberOfDimensions(prhs[0]);
check out the mex documentation.
Or, you can use Python with numpy for matrices, and use Pyrex for the
c-extensions and make your life a *lot* easier.
