Description: Relaxation method referred to as SOR method, also called relaxation hair, the basic idea is iterative, that is, the Gaussian method has been derived x (i), x (i-1), based on the combination of the new sequence, thus speeding up the convergence rate . Out the main elements used in the Gauss elimination method is the elimination of the strong conditions, that is, Ai is nonsingular, successive elimination unknown. As long as the equations of non-singular coefficient matrix, equations have a unique solution. This column pivoting on, called out the main elements of elimination. The application conditions for each main element of change is not equal and non-singular coefficient matrix Ai.
