What are the different iteration methods and how do they compare in performance?

There are several iteration methods, including the Jacobi method, Gauss-Seidel method, and Successive Over-Relaxation (SOR). Each has its strengths and weaknesses depending on the problem.

Can you explain how the Jacobi method works?

Sure! The Jacobi method is an iterative algorithm used to solve a system of linear equations. It updates each variable based on the average of the neighboring variables from the previous iteration.

What are the advantages of using the Gauss-Seidel method over Jacobi?

The Gauss-Seidel method typically converges faster than the Jacobi method because it uses the most recent values of the variables as soon as they are available.

Are there specific scenarios where one method is preferred over the others?

Yes, for sparse matrices, the SOR method is often preferred due to its faster convergence. The choice depends on the matrix properties and the desired accuracy.
