Schödinger Functional

    function setbndfield(U, phi, lp::SpaceParm)

Sets abelian boundary fields with phases phi[1] and phi[2] to the configuration U at time salice $x_0=0$.

sfcoupling(U, lp::SpaceParm, gp::GaugeParm, ymws::YMworkspace)

Measures the Schrodinger Functional coupling ${\rm d}S/{\rm d}\eta$ and ${\rm d}^2S/{\rm d}\eta d u$.
