GMstab
GMstab is a robust
implementation of IDR(s)stab(L) and M(s)stab(L). The method is based on
an interior restarted GMRES method of length L*(s+1). The value for L
is chosen adaptively between 1 and 2. Flying restart and convergence
maintenance techniques are utilized in order to yield a maximum of
robustness and superlinear convergence improvements. Please download,
