Data supporting publication. Contains codes to create data, initial conditions and figure files, as well as original paper and explanatory "note". Optimization.m : Main routine for optimization (use param.m to specify the flow parameters, mixing norms, resolution etc.)

Diagnostic_diag.m : Main routine for diagnostic (forward integration in time only). Use param.m again. The *_diag.m routines are called for diagnostic only.

Flow_measures.m and Flow_measures_diag.m contain the definitions of all the diagnostic variables. Their timeseries are stored in norms_timeseries.mat.

All the figures have been produced with the data stored in norms_timeseries.mat and the flow snapshots. Omega0.mat is produced by Diagnostic_diag.m and contains the initial vorticity field for the perturbation.
