mathematical matrix

A rectangular array of numbers in row and column format. The numbers can be integers or floating point. Mathematical matrices are used in linear algebra, physics, engineering, computer graphics and gaming, data science and statistics and artificial intelligence (AI).

For rendering an image on every monitor and display screen, each digital frame is a matrix of pixels. For AI, a neural network is a system built entirely out of matrices and matrix computations. Following is a simple mathematical matrix. See AI secret sauce, integer and floating point.
