Requires YALMIP and SeDuMi

Certifying Lyapunov functions and multipliers in Example 1: Van der Pol equations
Single Lyapunov function Pointwise Max of 2 Lyapunov functions
Function to check SOS conditions: ex1_1V_checksos.m Function to check SOS conditions: ex1_2V_checksos.m
Quadratic V: ex1_1V2.mat Quadratic V: ex1_2V2.mat
Quartic V: ex1_1V4.mat Quartic V: ex1_2V4.mat
6th order V: ex1_1V6.mat 6th order V: ex1_2V6.mat
 

Certifying Lyapunov functions and multipliers in Example 2: 3D system
