Create the coarse 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 (hard coded to 0 when CoarseOp is called) |
