[SciPy-user] Need very simple example showing how to return numpy array from C/C++ function
Thu Dec 27 16:04:11 CST 2007
The problem is that you will have to copy yout data anyway. One of the best
solutions is to pass an already created Numpy array (as argument or with a
callback function) that you will be able to use (this is what I do with a
custom C++ array class that wraps the Python object).
