Preconditioned Jacobi iterative methods of stictly diagonally dominant L-matrices
The preconditioned Jacobi iterative method is discussed.It is proved theoretically that the preconditioned factor can accelerate the convergence speed of Jacobi iterative method,when the coefficient matrix is the strictly diagonally dominant L-matrix.Three numerical examples are given to demonstrate the effectiveness of the preconditioned Jacobi iterative method of the strictly diagonally dominant coefficients matrix.
