Guass Jordan elimination Method

This code is used to find solution for linear system AX=B or used to find the inverse of a matrix

% ============================ Solving Linear equations =============================

% Input: gjem(A,B)

% System AX = B;

% A is n-by-n matrix and B is n-by-1 matrix

% gjem(A,B) will return a n-by-1 matrix(X) which is solution to the System AX = B

%================================= Matrix inversion ================================

% Input: gjem(A,B)

% A is n-by-n matrix and B is n-by-n Identity matrix

% gjem(A,B) will return a n-by-n matrix(X) which is inverse of Matrix A
