Jacobi Method

The Jacobi method (a.k.a. the Jacobi iteration method) is an iterative algorithm used for solving a system of linear equations ( ).

This method is particularly useful for large systems where direct methods, such as Gaussian Elimination, are computationally expensive.

  1. Initialization: Start with an initial guess for ( ).
  2. Iteration: For each equation ( i ), update ( ) using:

  • where ( ) are the diagonal elements of ( A ), and ( } ) are the off-diagonal elements.
  1. Convergence: Repeat the iteration until the changes in are below a certain tolerance or until a maximum number of iterations is reached.
