[C++-sig] Accessing 2D array from python in C++

[alfa]

Hi John,

"You can call the expose_converters< npy_double >() function to expose multiarrays of doubles to python as numpy arrays."

I'm afraid you understood that I have a C++ array that is to be exposed in Python. Actually, my problem is the other way around in which I have a Python array that needs to be converted to/ exposed in C++.

Thanks in advance.

Also look in python_test/test_man.py for code that tests the
implementation from the python side if it helps.
