Create the coarse twisted-clover operator.
Takes the multigrid transfer class, which knows about the coarse grid blocking, as well as having prolongate and restrict member functions, and returns color matrices Y[0..2*dim-1] corresponding to the coarse grid hopping terms and X corresponding to the coarse grid "clover" term.
T[in] | Transfer operator defining the coarse grid |
Y[out] | Coarse link field |
X[out] | Coarse clover field |
kappa | Kappa parameter for the coarse operator |
mass | Mass parameter for the coarse operator (gets explicitly built into clover, hard coded to zero for non-staggered ops) |
mu | TM mu parameter for the coarse operator |
mu_factor | multiplicative factor for the mu parameter |
