DiscretizedSpaceElement.conj

DiscretizedSpaceElement.conj(self, out=None)

Complex conjugate of this element.

Parameters

outDiscretizedSpaceElement, optional

Element to which the complex conjugate is written. Must be an element of this element’s space.

Returns

outDiscretizedSpaceElement

The complex conjugate element. If out is provided, the returned object is a reference to it.

Examples

>>> discr = uniform_discr(0, 1, 4, dtype=complex)
>>> x = discr.element([5+1j, 3, 2-2j, 1j])
>>> y = x.conj()
>>> print(y)
[ 5.-1.j,  3.-0.j,  2.+2.j,  0.-1.j]

The out parameter allows you to avoid a copy:

>>> z = discr.element()
>>> z_out = x.conj(out=z)
>>> print(z)
[ 5.-1.j,  3.-0.j,  2.+2.j,  0.-1.j]
>>> z_out is z
True

It can also be used for in-place conjugation:

>>> x_out = x.conj(out=x)
>>> print(x)
[ 5.-1.j,  3.-0.j,  2.+2.j,  0.-1.j]
>>> x_out is x
True
