Detailed Description

GMRES(m) algorithm with complex variables.

This class implements GMRES(m) algorithm for nonhermitian matrix. The matrix is nonsymmetric matrix, and 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]
