Weighting

class odl.core.space.weightings.weighting.Weighting(impl, device, exponent=2.0)

Bases: object

Abstract base class for weighting of finite-dimensional spaces.

This class and its subclasses serve as a simple means to evaluate and compare weighted inner products, norms and metrics semantically rather than by identity on a pure function level.

The functions are implemented similarly to Operator, but without extra type checks of input parameters - this is done in the callers of the LinearSpace instance where these functions are being used.

__init__(impl, device, exponent=2.0)

Initialize a new instance.

Parameters

implstring

Specifier for the implementation backend

device :

device identifier, compatible with the backend associated with impl

exponentpositive float, optional

Exponent of the norm. For values other than 2.0, the inner product is not defined.
