Using NumPy for array and matrix math in Python Many mathematical operations, especially in machine learning or data science , involve working with matrixes , or lists of numbers.

The most common scenario for using Cython with NumPy is one where you want to take a NumPy array, iterate over it, and perform computations on each element that can’t be done readily in NumPy.

But, most matrix programming languages use the multiplication element to mean matrix multiplication. This is something to keep in mind when you start using Python. To get a true matrix multiplication, ...
