It is a numerical method that employs an iterative approach. Its counterpart for a single linear equation is the successive substitution or fixed-point iteration. It asks the user the coefficient and the RHD (Right-hand side) values matrix. It also lets the user choose which termination criterion to have, whether a %relative error or number of iterations. It checks if the system is diagonally dominant; if not, it would re-arrange the equations in the most diagonally dominant form possible, ensuring convergence. If the given system cannot be totally diagonally dominant, it alerts the user.
