Requirements

• Matlab R2021b
• Sedumi
• Yalmip

How to use it

Open the example3_1.m file in matlab and run the script. The three figures below should open.

Figure 1 shows the graph of $V(x)$ inside set $Z$. The minimum value of $V$ in the boundary of $Z$ is $b$.

Figure 2 shows the contour plot of $V$ superposed by the boundary of set $\mathcal{D}$, in black. Using the level sets, we can find $l$, the maximum value of $V$ inside $\mathcal{D}$.

Figure 3 shows the level sets $\Omega_L,\Omega_l$ and the set $\mathcal{D}$.
