Detailed Description

BiCGStab(DS_L) algorithm.

This class implements BiCGStab(DS_L) algorithm for nonhermitian matrix. The product of vectors is treated in complex. See T.Miyauchi et al, Trans.J.SIAM 11 (2) (2001) 49. 22 Jan 2012 Y.Namekawa YAML is implemented. [14 Nov 2012 Y.Namekawa] Multi-threaded. [17 Jul 2014 Y.Namekawa] Introduce unique_ptr to avoid memory leaks. [21 Mar 2015 Y.Namekawa] Add restart. [22 Feb 2016 Y.Namekawa] Add flop_count. [ 8 Aug 2016 Y.Namekawa]
