Programming Question

The domain of attraction is solved using SOS optimization with reference to thedifferential equations in these two papers.
The differential equations that need to be finally solved are:
方法步骤：
Method Steps:
Write the solution equations using matlab, indicating the solver used.
SOSTOOLS may or may not be used.The resulting approximate graph (only SOS
part is drawn)

NOTE:
I will want to see an iteration of these two parameters in the program? That’s
what I will want to see well. If you will make a video showing it before
submitting the code file, that will be better off.
According to this image, V is also updated iteratively. Please show me how this
program is handled? If you can a short summary, that will help me so much.
