The code uploaded here reproduces 2 figures (Figure 8 and Figure 9) from [1]. The core scripts to run are
Figure_8.m
Figure_9.m
In order for these scripts to run, they must be retained in the existing folder structure as this zip, or the sub-functions have to be added to the path in MATLAB’s path. Figure_8 reproduces the training, testing, and rescaled testing of the Rossler system while Figure 9 reproduces the training, testing, and rescaled testing of the pitchfork normal form system.
