Acceleration techniques for iterative methods for linear systems of both static (Qy = b) and dynamic (y 0 = Qy+g(t)) type are analyzed. A new splitting Q = M ? N, where M is block-Toeplitz is proposed. In the static case considerable improvement is observed, while in the dynamic case this preconditioning results only in a slightly faster waveform relaxation… CONTINUE READING
