New Example
===============

This release adds a new example,  :doc:`/libraries/savings/savings_example4` in :mod:`~savings`.
The example shows how to profile and optimize a model using ``CashValue_ME_EX1`` as an example.
The optimization approach involves replacing pandas DataFrames and Series with numpy arrays.
The optimized model used in the example is included in :mod:`~savings` as ``CashValue_ME_EX4``.
The example is based on recommendation given by `alexeybaran <https://github.com/fumitoh/modelx/discussions/79>`_
