FunctionOperator

class FunctionOperator(func, operator, func_name=None)[source]

Bases: AbstractSubsystemOperator

A function applied on an operator. This assumes the output is the same shape/dimension as the input.

Initialize.

Parameters:

  • func – The function.

  • operator – The operator.

  • func_name – The name of the function.

Methods

base_matrix()[source]

Return the matrix defined on the internal subsystems.

matrix(ordered_subsystems=None)

Build the matrix for the operator relative to the ordered subsystems.

remove_subsystems(subsystems)

Return operator with subsystems removed.

Components of operators with support on removed subsystems will be set to 0.

Return type:

AbstractSubsystemOperator

restrict_subsystems(subsystems)

Reduce the operator to the list of subsystems.

Components of operators with support on removed subsystems will be set to 0.

Return type:

AbstractSubsystemOperator

Attributes

func

The function applied to the operator.

subsystems

Get the subsystems the operator acts on.
