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
neo	baa382f055	Added check of mpfr and gmp at configure time ... It generates automatically the linker flags or complains if not found.	2015-05-19 13:54:55 +09:00
Peter Boyle	11cb3e9a01	Getting closer to having a wilson solver... introducing a first and untested ... cut at Conjugate gradient. Also copied in Remez, Zolotarev, Chebyshev from Mike Clark, Tony Kennedy and my BFM package respectively since we know we will need these. I wanted the structure of algorithms/approx algorithms/iterative etc.. to start taking shape.	2015-05-18 07:47:05 +01:00
