Gaussian elimination - Wikipedia
https://en.wikipedia.org/wiki/Gaussian_eliminationIn mathematics, Gaussian elimination, also known as row reduction, is an algorithm for solving systems of linear equations. It consists of a sequence of operations performed on the corresponding matrix of coefficients. This method can also be used to compute the rank of a matrix, the determinant of a square matrix, and the inverse of an invertible matrix. The method is named after Carl Friedrich Gauss(1777–1855) although some special cases of the method—albe…
The Gauss-Jordan Elimination Algorithm
people.math.umass.edu › ~havens › m235LecturesWe present an overview of the Gauss-Jordan elimination algorithm for a matrix A with at least one nonzero entry. Initialize: Set B 0 and S 0 equal to A, and set k = 0. Input the pair (B 0;S 0) to the forward phase, step (1). Important: we will always regard S k as a sub-matrix of B k, and row manipulations are performed simultaneously on the ...
Gauss-Jordan Elimination Calculator
matrix.reshish.com › gauss-jordanEliminationForward elimination of Gauss-Jordan calculator reduces matrix to row echelon form. Back substitution of Gauss-Jordan calculator reduces matrix to reduced row echelon form. But practically it is more convenient to eliminate all elements below and above at once when using Gauss-Jordan elimination calculator. Our calculator uses this method.
