Gauss Seidel Method C Program


2 Ways For Gauss Seidel Method in C Programming

Let’s understand the Gauss-Seidel method in numerical analysis and implement Gauss Seidel method in C programming language.

What is Gauss Seidel Method?

The Gauss Seidel method is an iterative process to solve a square system of multiple linear equations. It also is popularly known as Liebmann method.


In an iterative method in numerical analysis, every solution attempt is started with an approximate solution of an equation and iteration is performed until the desired accuracy is obtained.

In Gauss-Seidel method, the most recent values are used in successive iterations. The Gauss-Seidel Method allows the user to control round-off error.

The Gauss Seidel method is very similar to Jacobi method and is called as the method of successive displacement.

The Gauss Seidel convergence criteria depends upon the following two properties:

  1. The matrix is diagonally dominant
  2. The matrix is symmetrical and positive – definite
