Numerical Computation and Optimization Solution of Linear Algebraic Equations Gaussian Elimination Gauss-Jordan method By Assist Prof. Dr. Ahmed Jabbar https://dr-ahmedjabbar.weebly.com/msc-students.html

Gauss-Jordan method The Gauss-Jordan method is a variation of Gauss elimination. The major difference is that when an unknown is eliminated in the Gauss-Jordan method, it is eliminated from all other equations rather than just the subsequent ones. In addition, all rows are normalized by dividing them by their pivot elements. Thus, the elimination step results in an identity matrix rather than a triangular matrix (Fig. 9.9). Consequently, it is not necessary to employ back substitution to obtain the solution. The method is best illustrated by an example. https://dr-ahmedjabbar.weebly.com/msc-students.html
