Figure 2
--------

Figure 2 is a 3D representation of SINDy error data created from the SINDy runs exploring the
sweeping of hyperparameters. It is included as an EXAMPLE of how SINDy results can be
investigated, from before we switched to using Gurobi.

The figure is generated by Python:-
sindy-stuff/old/run-Ra-1e6/plot3d.py

The complete raw data can be generated from:-
sindy-stuff/old/run-Ra-1e6/run-Ra-1e6.sh
and the SINDy script:-
sindy-stuff/old/run-Ra-1e6/bulktest-files1-8-int300.py
which generates a file:-
bulktest.txt
when run on HPC

Newer data files generated using the Gurobi optimiser can be found in text 
format (*.txt) in the following directories from newer analyses:-
sindy-stuff/Ra-1e8/*.txt
sindy-stuff/Ra-1e10/*.txt

and can be plotted with:-
sindy-stuff/old/run-Ra-1e6/plot3d.py

NOTE: the SINDy library that was used can be found in each directory in order to force its use and
overriding anything installed in the environment, e.g.:-
sindy-stuff/pysindy/

WARNING: Not using this library can cause component swap issues for some reason we do not fully understand
tied to declaration of the custom library within each version of SINDy.
