$ unzip bdtoolkit-2017c.zipEach dynamical system (model) is defined by a specially formatted data structure that we call a sys struct. An existing sys struct can be loaded from a mat file or a new one can be constructed from a model-specific script. The models directory contains both scripts and mat files for numerous dynamical systems. The following example shows how to load the pre-defined sys struct for the Hindmarsh-Rose model from a mat file into the graphical toolbox (bdGUI).
>> addpath bdtoolkit
>> addpath bdtoolkit/models
>> load HindmarshRose.mat sysIt allows the user to vary the model's parameters and solve the dynamical equations by forward-integration.
