Induced Dimension Reduction (IDR)
method
Click
here to find out more about IDR(s): papers, MATLAB code and
examples. IDR(s) is a new,
highly efficient Krylov method for solving large sparse nonsymmetric
systems of linear equations. The figure shows the
convergence of IDR(s) and Bi-CGSTAB for a Helmholtz problem.
IDR(s) is a short recurrence method. The overhead per iteration is
comparable with that of Bi-CGSTAB.
