Module iterative 

Iterative solvers for linear systems

This module provides Krylov subspace methods for solving large sparse systems:

• gmres: GMRES(m) with restart - best for general non-symmetric systems
• bicgstab: BiCGSTAB - good alternative to GMRES
• cgs: CGS - faster but less stable than BiCGSTAB
• cg: Conjugate Gradient - for symmetric positive definite systems
