Peter Boyle	1fcacef239	Mobius Caley form, Mobius Zolotarev operators. Pass Even Odd vs unprec test and hermiticity checks ... in tests/Grid_any_evenodd.cc; will work on inversion tests shortly.	2015-06-03 09:36:26 +01:00
Peter Boyle	3845f267cb	Domain wall fermions now invert ; have the basis set up for ... Tanh/Zolo * (Cayley/PartFrac/ContFrac) * (Mobius/Shamir/Wilson) Approx Representation Kernel. All are done with space-time taking part in checkerboarding, Ls uncheckerboarded Have only so far tested the Domain Wall limit of mobius, and at that only checked that it i) Inverts ii) 5dim DW == Ls copies of 4dim D2 iii) MeeInv Mee == 1 iv) Meo+Mee+Moe+Moo == M unprec. v) MpcDagMpc is hermitan vi) Mdag is the adjoint of M between stochastic vectors. That said, the RB schur solve, RB MpcDagMpc solve, Unprec solve all converge and the true residual becomes small; so pretty good tests.	2015-06-02 16:57:12 +01:00
