I would like to design a GUI in-app design for speech/acoustic signal processing. I don't know what to do to plot a real-time sine wave graph

  1. Create a new App Designer app by selecting "App Designer" from the MATLAB Home tab.
  2. Drag and drop an axes component onto the app design canvas.
  3. Add the following code to the app's startup function to initialize the axes and create a line object for the sine wave:
function startupFcn(app)
% Set the x and y limits of the plot
xlim(app.UIAxes, [0, 2*pi]);
ylim(app.UIAxes, [-1, 1]);
% Create a line object for the sine wave
app.Line = animatedline(app.UIAxes);
end
4. Add an updatePlot function to continuously update with new data.
5.Add a timer component to the app by dragging and dropping it onto the design canvas.
6.Set the timer's period to the desired refresh rate (e.g., 0.1 seconds).
7. Add the call to the updatePlot function in timer's timerFcn callback.
