In earlier tutorials, we’ve already gone through the C program and algorithm/flowchart for Gauss-Seidel method. In this method, just like any other iterative method, an approximate solution of the given equations is assumed, and iteration is done until the desired degree of accuracy is obtained. Gauss-Seidel is considered an improvement over Gauss Jacobi Method. Gauss-Seidel Method Theory: Gauss-Seidel Method in MATLAB: Gauss-Seidel Method Example:
