sigpy.linop.Vstack

class sigpy.linop.Vstack(linops, axis=None)

Vertically stack linear operators.

Creates a Linop that applies linops independently, and concatenates outputs. In matrix form, this is equivalant to given matrices {A1, …, An}, returns [A1.T, …, An.T].T.

Parameters:

• linops (list of Linops) – list of linops with the same input shape.
• axis (int or None) – If None, outputs are vectorized and concatenated.

__init__(linops, axis=None)

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__(linops[, axis])	Initialize self.
apply(input)	Apply linear operation on input.

Attributes

H	Return adjoint linear operator.
N	Return normal linear operator.
