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.

Codes: If you intend to use the software, please do not forget to place the proper acknowledgements.
