SALI code for detecting chaos in the FO chaotic systems

This code is designed for detecting chaos in the FO continues chaotic systems.

The code is designed based on the following papepr.
He Shaobo, Sun Kehui, Yuexi Peng. Detecting chaos in fractional-order nonlinear systems using the smaller alignment index [J]. Phys. Lett. A, 2019, 383(19): 2267-2271.
It provives an effective and new way for dynamical analysis of fractional chaotic systems.
In the code, the fractional-order continues is solved by the ABM algorithm and the "fde12.m" function is used. The detail of the code can be dowloaded in the following link.
