The comments in the code are indicated by the percent sign so that the reader has an easier
understanding of each command. Using the MATLAB command >> help ode23, the MATLAB
function is studied first and then utilized. Moreover, this function is calling the function diffa
written by the users. It should be noted that if another high-level programming language was
used to perform these simulations, it would have taken a lot of time. These simulations
demonstrate how powerful and useful MATLAB is. The simulation results are illustrated in
figure 5. The current through the inductor and the voltage across the capacitor hold physically
and as expected.
