sigpy.linop.Hstack

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

Horizontally stack linear operators.

Creates a Linop that splits the input, applies Linops independently, and sums outputs. In matrix form, this is equivalant to given matrices {A1, …, An}, returns [A1, …, An].

Input and output devices must be the same.

Parameters:

• linops (list of Linops) – list of linops with the same output shape.
• axis (int or None) – If None, inputs are vectorized and concatenated. Otherwise, inputs are stacked along axis.

__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.
