In 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—albeit pres… Web11 LINEAR ALGEBRA Gauss-Jordan Method for computing the inverse We can perform row operations on A and I simultaneously by constructing a “superaugmented matrix” Theorem ** shows that if A is row equivalent to I, (which, by the Fundamental Theorem (<) (.), means that A is invertible), then elementary row operations will yield The procedure ...

WebJan 16, 2024 · I'm calculating an inverse matrix using Gauss-Jordan algorithm. I'd like to use pivoting (with swapping rows, just like in standard Gauss algorithm) in order to avoid division by zero in some cases. But I also noticed that interchanging rows affects inverse matrix and I don't fully understand how could I avoid division by zero on when running ... WebMar 24, 2024 · Gauss-Jordan Elimination.
