R = rref(A) produces the reduced row echelon form of A using Gauss Jordan elimination with partial pivoting. 2 Apr Gauss Jordan Implementation % By Khaled Sharif % % Description: % This function will take a matrix designed to be used by the % Gauss-Jordan algorithm and solve it, returning a transposed % version of the last column in the ending matrix which % represents the solution to the unknown variables. Gauss-Jordan method. [m,n]=size(a);. for j=1:m for z=2:m. if a(j,j)==0. t=a(1:);a( 1:)=a(z:); a(z:)=t;. end. end. for i=j+1:m. a(i:)=a(i:)-a(j:)*(a(i,j)/a(j,j));. end. end. for j=m: for i=j a(i:)=a(i:)-a(j:)*(a(i,j)/a(j,j));. end. end. for s=1:m. a(s:)= a(s:)/a(s,s);. x(s)=a(s,n);. end. disp('Gauss-Jordan method:');. a. x'.

Anyway, the command to do Gauss-Jordan reduction, known in MATLAB as “reduced row-echelon form”, is >>rref(A) as found by other means. Looking ahead, MATLAB will solve linear equations in matrix form more easily than MAPLE, again due to the default assumption that anything entered is to be treated like a matrix.
7 Mar Gauss Jordan Elimination & Pivoting is the most crafty device for solving a set of n variables with given n equations. 19 May Gauss-Jordan Method in Matlab. Program with source code in MATLAB, along with theory, working steps, output, and an example. This program performs the matrix inversion of a square matrix step-by-step. The inversion is performed by a modified Gauss-Jordan elimination method. We start with an arbitrary square matrix and a same-size identity matrix.
