Well, it really depends on how you want to do it.  Are you doing it
from the Python side of things or from C/C++?  If its C you need to
just look at the NumPy C API to figure out what you have to do.  NumPy
arrays has an array of char* with an array of ints (strides)
describing the strides along each dimension of the (multidimensional)
array.  The NumPy docs has all the necessary information.
