class Multifield2Vector(domain)

Bases: LinearOperator

Flatten a MultiField and return a Field with unstructured domain and the same number of degrees of freedom.

Parameters:

domain (MultiDomain) – Domain of the operator

This operator works only on MultiFields that have the same dtype for all entries.

__init__(domain)

apply(x, mode)

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

Parameters:

• x (nifty8.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.
