          |  |  Liapunov functions allow the determination of stability for non- linear systems without the need to find exact solutions. The Variable Gradient Method provides a systematic approach to determining a suitable Liapunov function. This package automates the steps involved in generating a Liapunov function using the Variable Gradient Method. The notebook provides an overview of the theory behind non-linear stability analysis and a discussion of how to interact with the package, as well as some examples.
