【 摘 要 】
Matrix compensation is introduced to preserve the positivity of matrices when we construct preconditioners for positive-definite matrices. Diagonal compensation for symmetric positive-definite matrices is generalized to positive-definite matrices. If matrix compensation is used to construct preconditioners, condition numbers of preconditioned matrices are estimated.
