摘要
In a preconditioning process for an iteration method to solve simultaneous linear equations through multilevel block incomplete factorization of a coefficient matrix, a set of variable numbers of variables to be removed is determined at each level of the factorization such that a block matrix comprising coefficients of the variables can be diagonal dominant. The approximate inverse matrix of the block matrix is obtained in iterative computation, and non-zero elements of a coefficient matrix at a coarse level are reduced.
