PythonCExtensions

Using a Python C extension and comparing its performance to NumPy and Python

You need to build the C extension before running this. To build and install the extension run:

$ python3 setup.py install

stdtest.py has a main method which will compare Python, NumPy and the C extension for small arrays and plot the performance with matplotlib.

I've modified the wrapper to work both Python 2 and 3.
