Try putting this at the top of the file and then mex it:
// One input argument: The Filename
int main(int argc, char **argv);
#include "mex.h"
void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
{
int argc = 2;
char *argv[2];
if( nrhs == 1 && mxIsChar(prhs[0]) ) {
argv[1] = mxArrayToString(prhs[0]);
main(argc,argv);
mxFree(argv[1]);
} else {
mexErrMsgTxt("Expected one input, the filename");
}
}
