Using Matrices
Completion requirements
Technically speaking, vectors and matrices are mathematical objects usually applied within the context of linear algebra. An array, on the other hand, is the computer science data structure used to represent a matrix. So, for example, a vector can be stored in a one-dimensional array. A matrix can be stored in a two-dimensional (or "double subscript") array. Much of data science depends upon using arrays (often multi-dimensional) containing numerical data. Before delving into the numpy module, use this playlist to review basic vector and matrix operations.
