NumPy is known for being fast, but there's always room for improvement. Learn how to use Cython to iterate over NumPy arrays at the speed of C.

import numpy as np def calculate (data_list): """ Calculates mean, variance, standard deviation, max, min, and sum of rows, columns, and flattened elements for a 3x3 matrix.

The conversion from C-ordered Numpy arrays to Fortran-ordered data is extremely slow and memory intensive. The operation takes several multiples of the time it takes to load the data from disk.
