Vectors and Matrices are created as instances of a numpy array. We can think of a 1D NumPy array as a list of numbers (or row- vector), and a 2D number array as a matrix.

The * means the namespace for all functions in SymPy are loaded, so we can call them directly without having to preface them with the package name. Vectors and Matrices are created as instances of a ...

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 ...
