permanent

Implements Ryser's algorithm for the permanent.

Install:

$ pip install permanent

Use:

>>> from numpy import *
>>> from permanent import permanent
>>> permanent(eye(15))
(1-0j)

Please note that the function assumes that the array contains complex numbers. So for example:

>>> permanent(array([[0,1],[1,1]]), dtype=complex)
(1+0j)

whereas using permanent(array([[0,1],[1,1]])) will not produce the expected result.
