A class of preconditioners for solving non-Hermitian positive definite systems of linear algebraic equations is proposed and investigated. It is based on Hermitian and skew-Hermitian splitting of the initial matrix. A generalization for saddle point

An algorithm that is a modification of Hermitian and skew-Hermitian splitting is considered to be used to solve a large system of linear algebraic equations with a saddle point. The method is applied to solve constrained optimization problems. The nu
