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.

If you are doing matrix-based or array-based math and you don’t want the Python interpreter getting in the way, use NumPy. By drawing on C libraries for the heavy lifting, NumPy offers faster ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Gray Scale We've already covered how to convert an image to gray scale in the Image Manipulation Basics section. However, we can also do this using matrix multiplication. There are two gray scale ...
