Does the mex files generated on my PC work on another PC?

I developed a software with Matlab. In order to speed up the software executions, I would like to buy the Matlab Coder toolbox to generate mex files for the software. Because the software is going to be used by other students and scientists, I wonder whether the mex files generated on my PC is going to work on other PCs. Many thanks.

Yes, provided that they are running with the same bits (32 vs 64) as you compiled for.

Note however that there has never been any promises about backwards compatibility for .mex* files, so the binary files you generate might stop working at some future release.

If you use MATLAB Coder to generate C code then you could distribute the C code, which the user could then compile; that should be a bit more robust against future changes to MATLAB.

Walter, Many thanks for your answer. Further question: Does user's Matlab need the Matlab Coder toolbox to run my software which uses mex files?

[Walter Roberson]

No, only the person generating the code needs MATLAB Coder.
