pygsti.modelmembers.operations.opfactory.op_from_factories

op_from_factories(factory_dict, lbl)

Create an operator for lbl from the factories in factory_dict.

If the label has arguments, then this function looks for an operator factory associated with the label without its arguments. If one exists, the operator is created by calling OpFactory.create_simplified_op(). with the label’s arguments. Otherwise, it looks for a factory associated with the label’s name (lbl.name) and passes both the labe’s state-space-labels and arguments (if any) to OpFactory.create_simplified_op().

Raises a KeyError if a matching factory cannot be found.

Parameters:

• factory_dict (dict) – A dictionary whose keys are labels and values are OpFactory objects.

• lbl (Label) – The label to build an operation for.

Return type:

LinearOperator
