LinCombOperator

class odl.LinCombOperator(*args, **kwargs)

Bases: Operator

Operator mapping two space elements to a linear combination.

Implements:

LinCombOperator(a, b)([x, y]) == a * x + b * y

__init__(space, a, b)[source]

Initialize a new instance.

Parameters

spaceLinearSpace: Space of elements which the operator is acting on.
a, bspace.field elements: Scalars to multiply x[0] and x[1] with, respectively.

Examples

>>> r3 = odl.rn(3)
>>> r3xr3 = odl.ProductSpace(r3, r3)
>>> xy = r3xr3.element([[1, 2, 3], [1, 2, 3]])
>>> z = r3.element()
>>> op = LinCombOperator(r3, 1.0, 1.0)
>>> op(xy, out=z)  # Returns z
rn(3).element([ 2.,  4.,  6.])
>>> z
rn(3).element([ 2.,  4.,  6.])
