Detailed Description

Maximum projection to SU(N) gauge group.

Maximum projection for SU(N) matrix by Cabibbo-Marinari method, SU(2) subgroup transformation. The code was originally written by Takashi Umeda (1997) in Fortran by explicitely assuming SU(3) group. Genralization to SU((N) was done by H.M. 09 Aug 2012 H.Matsufuru YAML is implemented. [14 Nov 2012 Y.Namekawa]
