Bode plot for input-output systems
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- `[#1051] Add Bode plot <https://github.com/pymor/pymor/pull/1051>`_
The :meth:`~pymor.models.iosys.InputOutputModel.bode_plot` method for creating a
Bode plot was added `[#1051] <https://github.com/pymor/pymor/pull/1051>`_,
complementing the :meth:`~pymor.models.iosys.InputOutputModel.mag_plot` method.
Additionally, the :meth:`~pymor.models.iosys.InputOutputModel.bode` method can
be used to compute the magnitudes and phases over the imaginary axis (for
continuous-time systems).
Make VectorArrays iterable
~~~~~~~~~~~~~~~~~~~~~~~~~~
- `[#1068] Make VectorArrays iterable <https://github.com/pymor/pymor/pull/1068>`_
VectorArrays are iterable
~~~~~~~~~~~~~~~~~~~~~~~~~
|VectorArrays| became iterable sequences with
`[#1068] <https://github.com/pymor/pymor/pull/1068>`_, i.e.,
`for v in V` can be used to work on individual vectors when needed.
Improved tutorial structure for system-theoretic methods
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- `[#1141] Restructure sys-mor tutorial <https://github.com/pymor/pymor/pull/1141>`_
- `[#1160] remove notebooks dir <https://github.com/pymor/pymor/pull/1160>`_
A tutorial on linear time-invariant systems was added
(:doc:`tutorial_lti_systems`) and the existing balanced truncation tutorial was
appropriately simplified (:doc:`tutorial_bt`)
`[#1141] <https://github.com/pymor/pymor/pull/1141>`_.
Additionally, the Jupyter notebooks from the `notebooks/` directory were
converted to demos `[#1160] <https://github.com/pymor/pymor/pull/1160>`_,
`[#1198] <https://github.com/pymor/pymor/pull/1198>`_.

@@ -70,27 +82,52 @@ Rename estimate/estimators methods of models
- `[#1041] Rename Model.estimate to Model.estimate_error and estimators to error_estimators <https://github.com/pymor/pymor/pull/1041>`_
Deprecate dot/pairwise_dot
~~~~~~~~~~~~~~~~~~~~~~~~~~
- `[#1066] Deprecate dot/pairwise_dot in favor of inner/pairwise_inner <https://github.com/pymor/pymor/pull/1066>`_
Deprecate dot and pairwise_dot
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
At first, |VectorArrays| only had `dot` and `pairwise_dot` methods for computing
inner products between vectors.
Later, more general methods `inner` and `pairwise_inner` were added to simplify
computing non-Euclidean inner products.
To reduce the list of methods for |VectorArrays|,
the `dot` and `pairwise_dot` methods are now deprecated and will be removed in
the next release `[#1066] <https://github.com/pymor/pymor/pull/1066>`_.
Restructuring of grid classes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- `[#1044] Restructuring of grid classes <https://github.com/pymor/pymor/pull/1044>`_
Model outputs changed from VectorArray to NumPy array
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- `[#1089] Let Model outputs be NumPy arrays <https://github.com/pymor/pymor/pull/1089>`_
The inheritance structure of grid classes was simplified
`[#1044] <https://github.com/pymor/pymor/pull/1044>`_.
In particular,
- `ConformalTopologicalGridDefaultImplementations`,
`ReferenceElementDefaultImplementations`,
`AffineGridDefaultImplementations`, and
`ConformalTopologicalGrid`
were removed,
- `AffineGrid` was renamed to `Grid`,
- `AffineGridWithOrthogonalCenters` was renamed to `GridWithOrthogonalCenters`.
Model inputs and outputs changed from VectorArray to NumPy array
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To simplify interoperability with third-party packages,
the model outputs, i.e., the results of :meth:`~pymor.models.interface.output`,
are not longer generic |VectorArrays|,
but NumPy arrays.
For consistency,
`input_space` and `output_space` were removed and
`input_dim` and `output_dim` were renamed to `dim_input` and `dim_output`
in :class:`~pymor.models.iosys.InputOutputModel`
`[#1089] <https://github.com/pymor/pymor/pull/1089>`_.
Renaming of some Operators
~~~~~~~~~~~~~~~~~~~~~~~~~~
- `[#1046] Append Operator to LinearAdvectionLaxFriedrichs, Concatenation and ComponentProjection <https://github.com/pymor/pymor/pull/1046>`_
For consistency in the naming of |Operators|,
`ComponentProjection`, `Concatenation` and `LinearAdvectionLaxFriedrichs` were
renamed to `ComponentProjectionOperator`, `ConcatenationOperator` and
`LinearAdvectionLaxFriedrichsOperator`, respectively.
`LinearAdvectionLaxFriedrichsOperator`, respectively
`[#1046] <https://github.com/pymor/pymor/pull/1046>`_.
