示例1: calcmom
void AlgFourierProp::calcmom(const FourMom& p)
{
char *fname="calcmom(const FourMom&)";
VRB.Func(cname,fname);
Float p1( p.x() + 0.5*bc[0] );
Float p2( p.y() + 0.5*bc[1] );
Float p3( p.z() + 0.5*bc[2] );
Float p4( p.t() + 0.5*bc[3] );
const Float PI(3.141592654);
p1 *= 2.0*PI/(GJP.XnodeSites()*GJP.Xnodes());
p2 *= 2.0*PI/(GJP.YnodeSites()*GJP.Ynodes());
p3 *= 2.0*PI/(GJP.ZnodeSites()*GJP.Znodes());
p4 *= 2.0*PI/(GJP.TnodeSites()*GJP.Tnodes());
Site site;
while ( site.LoopsOverNode() )
{
const Float px( site.physX()*p1 );
const Float py( site.physY()*p2 );
const Float pz( site.physZ()*p3 );
const Float pt( site.physT()*p4 );
const Float pdotx( px + py + pz + pt );
Rcomplex fact( cos(pdotx), -sin(pdotx) );
//--------------------------------------------
// Using AddMult is logically equivalent to
// momprop += fact * (*prop)[i]; ,
// but cuts down on the number of loops over
// the data. The time taken is reduced by
// a factor of two.
//--------------------------------------------
momprop.AddMult(fact,(*prop)[site.Index()]);
}
