You should use mxDuplicateArray, thats the documented way: #include “mex.h” void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[]) { plhs[0] = mxDuplicateArray(prhs[0]); }
You don’t really want to overload std::stringbuf, you want to overload std::streambuf or std::basic_streambuf (if you want to support multiple character types), also you need to override the overflow method as well. But I also think you need to rethink your solution to your problem. cout is just an ostream, so if all classes / … Read more
Which platform are you using? There are methods to help debug your MEX files. Whenever there is a segmentation fault, you can use an IDE to tell you where in the code it’s crashing.

After some experimenting with guidance from this page mentioned in the question, it seems like starting with an empty C++ project the following settings in the project’s Property Pages are necessary and sufficient to build a working .mexw64 from Visual Studio 2010: Configuration properties -> General: Set Target Extension to .mexw64 Set Configuration Type to … Read more
Why not adjust the mexopts.bat file in your directory? That way you can use the “mex” command transparently to compile anything, as usual in MATLAB, the same as if it was configured by MATLAB using mex -setup. I’m surprised nobody did this before. The file below is for x64 version of Matlab and Mingw. I’m … Read more
