triqs.gfs.descriptor_base.Const

class triqs.gfs.descriptor_base.Const(C)[source]

Bases: Base

Constant descriptor.

Fills the target Green’s function with a constant matrix (or scalar) on a frequency mesh. Used internally by convert_scalar_to_const() to lift scalar leaves of a lazy expression.

Parameters:

Cscalar or numpy.ndarray: Constant value. A scalar fills the diagonal of a square target space; a 2D array must match the target shape.

Methods

__call__(G)

Fill G.data with the stored constant on every mesh point.
