NumpyTensorSpace._inner

NumpyTensorSpace._inner(x1, x2)

Return the inner product of x1 and x2.

This function is part of the subclassing API. Do not call it directly.

Parameters:

x1, x2NumpyTensor

Elements whose inner product is calculated.

Returns:

innerfield element

Inner product of the elements.

Examples

>>> space = odl.rn(3)
>>> x = space.element([1, 0, 3])
>>> y = space.one()
>>> space.inner(x, y)
4.0

Weighting is supported, too:

>>> space_w = odl.rn(3, weighting=[2, 1, 1])
>>> x = space_w.element([1, 0, 3])
>>> y = space_w.one()
>>> space_w.inner(x, y)
5.0
