class pymor.algorithms.simplify.ContractRules[source]

Bases: pymor.algorithms.rules.RuleTable

Define algorithm by a table of match conditions and corresponding actions.

RuleTable manages a table of rules, stored in the rules attributes, which can be applied to given objects.

A new table is created by subclassing RuleTable and defining new methods which are decorated with match_class, match_generic or another rule subclass. The order of the method definitions determines the order in which the defined rules are applied.

Parameters

use_caching

If True, cache results of apply.

rules[source]

list of all defined rules.

action_ConcatenationOperator(self, op)[source]
action_LincombOperator(self, op)[source]
action_recurse(self, op)[source]

pymor.algorithms.simplify.contract(obj)[source]

Contract linear combinations and concatenations of Operators.

To any given Operator or Model, the following transformations are applied recursively:

Parameters

obj

Either a Model or an Operator to which the contraction rules are applied recursively for all children.

Returns

The transformed object.

pymor.algorithms.simplify.expand(obj)[source]

Expand concatenations of LincombOperators.

To any given Operator or Model, the following transformations are applied recursively:

Parameters

obj

Either a Model or an Operator to which the expansion rules are applied recursively for all children.

Returns

The transformed object.
