Detailed Description

BiCGStab algorithm.

This class implements BiCGStab algorithm for nonhermitian matrix. The product of vectors is treated in not complex but real. 22 Dec 2011 H.Matsufuru 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]
