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
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.
Cheers
Robin

I wonder if this is related to the fact that you can't unload a
dynamically linked module (like NumPy has). So, when you call
Py_Finalize you

How does the RTLD_GLOBAL thing manifest itself? So far I have only a
very basic start which basically consists of:
cmd = mxArrayToString(prhs[0]);
PyRun_SimpleString(cmd);
but I haven't noticed anything not working - I can run numpy

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

So far the only remotely tricky thing I did was redirect sys.stdout
and sys.stderr to a wrapper that uses mexPrintf so output goes to the
matlab console.
Be careful when you are using file handles. You have to be sure that
Matlab, Python and NumPy are all linked against the

Ah, I hadn't realised it was an OS constraint - I thought it was
possible to unload dlls - and that was why matlab provides the clear
function. mex automatically clears a function when you rebuild it - I
thought that was how you can rebuild and reload mex functions without

I was aware of this - I thought I would be OK on the mac - at least
Python and Numpy and my mex function are built with apple gcc although
I'm not sure about Matlab. I guess Windows will be more difficult...
