5: Gaussian Elimination

( \newcommand{\kernel}{\mathrm{null}\,}\)

This article discusses the Gaussian elimination algorithm, one of the most fundamental and important numerical algorithms of all time. It is used to solve linear equations of the form

Ax=b,

where A is a known N×N matrix, b is a known vector of length N, and x is an unknown vector of length N. The goal is to find x. The Gaussian elimination algorithm is implemented by Scipy's scipy.linalg.solve function.
