ScalingFunctional

class odl.functionals.default_functionals.ScalingFunctional(*args, **kwargs)

__init__(field, scale)

Initialize a new instance.

Parameters

fieldField

Domain of the functional.

scaleelement in domain

The constant value to scale by.

Examples

>>> field = odl.RealNumbers()
>>> func = ScalingFunctional(field, 3)
