Deflated Krylov software
Here some matlab files are given to implement a coarse grid projection
method. Deflation of the ICCG method is
first described in the paper:
C. Vuik and A. Segal and J.A. Meijerink
(pdf
file,
bibtex item)
An efficient preconditioned CG method for the solution
of a class of layered problems with extreme contrasts in the
coefficients
J. Comp. Phys., 152, pp. 385-403, 1999
Further references are available.
Deflation is also used in the
PARALUTION library which enables you
to perform various sparse iterative solvers and preconditioners on
multi/many-core CPU and GPU devices.

If you intend to use the software, please do not forget to place the
