numpy also uses row, column indexing
http://docs.scipy.org/doc/numpy/reference/generated/numpy.matrix.html
>>> import numpy
>>> m = numpy.matrix("1 2; 3 4; 5 6")
>>> m
matrix([[1, 2],
[3, 4],
[5, 6]])
>>> m[0]
matrix([[1, 2]])
>>> m[0,1]
2
This is the order I'd expect for any matrix implementation without
reading any docs too..
