- Abstract
Using tools like the Kronecker product and the vector operator, various Sylvester matrix equations can always be converted into the form A x = f , motivating us to investigate the algorithm for solving the linear matrix equation A x = f . By dividing the coefficient matrix A into row blocks or column blocks, a block-row iterative (BRI) algorithm, a block-column iterative (BCI) algorithm and an accelerated block-column iterative (ABCI) algorithm are developed to solve A x = f . It is successfully proved that the numerical solution produced by the proposed algorithms can converge to the exact solution for any given initial vector under appropriate conditions. Numerical examples are provided to demonstrate the effectiveness and superiority of the proposed algorithms.
