nifty.cl.operators.outer_product_operator module#

class OuterProduct(domain, field, flip=False)[source]#

Bases: LinearOperator

Performs the point-wise outer product of two fields.

Parameters:

  • domain (DomainTuple, the domain of the input field)

  • field (nifty.cl.field.Field)

  • flip (bool) – If False, field becomes the leading and the input field the trailing factor of the outer product, i.e. x -> field * x. If True, the order is reversed, i.e. x -> x * field. Default: False.

  • ---------

__init__(domain, field, flip=False)[source]#
apply(x, mode)[source]#

Applies the Operator to a given x, in a specified mode.

Parameters:

  • x (nifty.cl.field.Field) – The input Field, defined on the Operator’s domain or target, depending on mode.

  • mode (int) –

    • TIMES: normal application

    • ADJOINT_TIMES: adjoint application

    • INVERSE_TIMES: inverse application

    • ADJOINT_INVERSE_TIMES or INVERSE_ADJOINT_TIMES: adjoint inverse application

Returns:

The processed Field defined on the Operator’s target or domain, depending on mode.

Return type:

nifty.cl.field.Field
