FunctionalRightVectorMult

class odl.solvers.functional.functional.FunctionalRightVectorMult(*args, **kwargs)

Bases: Functional, OperatorRightVectorMult

Expression type for the functional right vector multiplication.

Given a functional func and a vector y in the domain of func, this corresponds to the functional

(func * y)(x) == func(y * x).

Attributes:

adjoint

Adjoint of this operator.

convex_conj

Convex conjugate functional of the functional.

domain

Set of objects on which this operator can be evaluated.

functional

grad_lipschitz

Lipschitz constant for the gradient of the functional.

gradient

Gradient operator of the functional.

inverse

Inverse of this operator.

is_functional

True if this operator's range is a Field.

is_linear

True if this operator is linear.

operator

The operator part of this multiplication.

proximal

Proximal factory of the functional.

range

Set in which the result of an evaluation of this operator lies.

vector

The fixed element to multiply with.

Methods

__call__(x[, out])	Return self(x[, out, **kwargs]).
bregman(point, subgrad)	Return the Bregman distance functional.
derivative(point)	Return the derivative operator in the given point.
norm([estimate])	Return the operator norm of this operator.
translated(shift)	Return a translation of the functional.

__init__(func, vector)

Initialize a new instance.

Parameters:

funcFunctional

The domain of func must be a vector.space.

vectordomain element

The vector to multiply by.
