How to generate PWM signal in MATLAB App Designer?

The provided content is about a video that demonstrates how to generate and plot a Pulse Width Modulation (PWM) signal in MATLAB App Designer’s UI Axes. The source code for the task is shared. It involves creating a class called PWMSignalApp with app components like UIAxes and PWMButton. After creating UIFigure and components, a function named PWMButtonPushed is declared. This function generates a sine wave and a PWM signal corresponding to it, plotting both signals on different UI Axes. The user is encouraged to direct any questions, suggestions, or appreciations to the provided contact email address.
