WebThe Jacobi method can generally be used for solving linear systems in which the coefficient matrix is diagonally dominant. ... If the linear system is ill-conditioned, it is most probably that the ... Webthen we say that the matrix is strictly diagonally dominant and if the inequality is greater than or equal to, then we can say that the matrix is weakly diagonal dominant .However, when these methods are combined with the more efficient methods, for example as a pre-conditioner, can be quite successful. For example see [3,4] ,It has
