class pypint.multi_level_providers.level_transition_providers.i_level_transition_provider.ILevelTransitionProvider(*args, **kwargs)[source]¶

Bases: builtins.object

Interface for level transition providers.

__init__(*args, **kwargs)[source]¶

Parameters:	num_fine_points (int) – (optional) Number of points of the fine level. num_coarse_points (int) – (optional) Number of points of the coarse level.

prolongate(coarse_data)[source]¶

Prolongates given data from the coarse to the fine level.

Parameters:	coarse_data (numpy.ndarray) – Coarse data vector to prolongate.
Returns:	prolongated data – Prolongated data on the fine level.
Return type:	numpy.ndarray
Raises:	ValueError – if coarse_data is not a numpy.ndarray if coarse_data has more or less entries than num_coarse_points

restringate(fine_data)[source]¶

Restringates given data from the fine to the coarse level.

Parameters:	fine_data (numpy.ndarray) – Fine data vector to restringate.
Returns:	restringated data – Restringated data on the coarse level.
Return type:	numpy.ndarray
Raises:	ValueError – if fine_data is not a :py:class:`numpy.ndarray if fine_data has more or less entries than num_fine_points

__weakref__¶

list of weak references to the object (if defined)

num_coarse_points[source]¶

Parameters:	prolongation_operator (numpy.ndarray) – New prolongation operator to be used.
Returns:	prolongation operator – Current prolongation operator.
Return type:	numpy.ndarray

restringation_operator[source]¶

Accessor for the restringation operator.

Parameters:	restringation_operator (numpy.ndarray) – New restringation operator to be used.
Returns:	restringation operator – Current restringation operator.
Return type:	numpy.ndarray
