Of course Peter Pearson's hint applies to my answer. The above function
doesn't exist, it should be numpy.linalg.matrix_rank()
>>> numpy.linalg.matrix_rank([[1,0,0], [0,1,0], [0,0,1]])
which should not be confused with numpy.rank() that just returns the number
>>> numpy.rank([[1,0,0], [0,1,0], [0,0,1]])
