Detailed Description

GMRES(m) algorithm with complex variables.

This class implements GMRES(m) algorithm for nonhermitian matrix. The product of vectors is treated in complex. See Y.Saad and M.H.Schultz, SIAM J.Sci.Stat.Comput. 7 (1986) 856. 8 Aug 2012 Y.Namekawa YAML is implemented. [14 Nov 2012 Y.Namekawa] Multi-threaded. [17 Jul 2014 Y.Namekawa] unique_ptr is introduced to avoid memory leaks [21 Mar 2015 Y.Namekawa]
