Function Documentation

void define_base_matrices

(

string

convention = "FERMILAB"

)

define convetion for Gamma matrices and bases of SU(2) and SU(3)

At the beginning of any FermiQCD program you MUST call

/// define_base_matrices("FERMILAB");
/// 

Possible convections are:

• "FERMILAB" (ok for lattice qcd)
• "MILC" (ok for lattice qcd)
• "UKQCD" (ok for lattice qcd)
• "Minkowsy-Dirac" (not ok for lattice qcd)
• "Minkowsy-Chiral" (not ok for lattice qcd) Convention can be changed within the program.
