Azusa Yamaguchi 8688ff8b3a multishift conjugate gradient added and a strong test: take a diagonal ... but non-identity matrix l1 0 0 0 .... 0 l2 0 0 .... 0 0 l3 0 ... . . . . . . . . . And apply the multishift CG to it. Sum the poles and residues. Insist that this be the same as the exactly taken square root where l1,l2,l3 >= 0.		2015-06-08 11:52:44 +01:00
