treams._operators.ExpandLattice

class treams._operators.ExpandLattice(lattice=None, kpar=None, basis=None, modetype=None, eta=0)

Expansion matrix in a lattice.

When called as attribute of an object it returns a suitable transformation matrix to expand one set of modes that is periodically repeated into another basis set. See also expandlattice().
