Be careful when you are using file handles. You have to be sure that
Matlab, Python and NumPy are all linked against the

Matlab MEX functions are DLLs, Python interpreter is a DLL, NumP

I get a similar but different error tryin
I forgot to add it doesn't happen if Py_Finalize isn't called - if I
take that out and just let the OS/matlab unload the mex function then
I can run it many times without the error, but it does leak a bit of
memory each time.

Hi,
I'm trying to embed Python in a MATLAB mex file. I've been coming
under some pressure to make my Python code available to my MATLAB
colleagues so I am trying to come up with a relatively general way of
calling numerical python code from Matlab.
I am making some progress - but get a reliable c
