Description
The Conjugate Gradient Squared method (CGS) has been proposed for solving large and sparse non-Hermitian linear systems, and it is well known that the CGS method may lead to a rather irregular convergence behaviour. In this paper, a Stabilized Conjugate Gradient Squared method (SCGS) is proposed as a variant of the CGS method. Numerical experiments indicate that the SCGS method is often more efficient than the CGS method.
