Hello,
I am trying to create an interactive plot GUI through AppDesigner.
I need to base the plot a given function:
I then need to generate a plot based off of the equation and what the user inputs.
I am currently struggling to code the callback for the plot button. Could somebody please tell me how (and it would greatly appreciated if you could show me complete code). This is what I have so far within a callback code for the plot button:
N=app.SinusoidsnEditField.Value;
A=app.app.AmplitudeAEditField.Value;
F=app.FundamentFreqHzDropDown.Value;
time=0:0.2:2;
syms n N
y=4*A/pi*1/(2*3-1)*sin(2*3-1)*2*pi*F*time;
plot(app.UIAxes,time,y);

Why did you edit your question again? Does the answer somehow not work? Then you should post a comment explaining why it doesn't solve the problem.
If you don't respond, I will revert your edit again and mark the answer as accepted.

I suggest to call the plot function just once (initially with default parameters at startup()). The returned object is a line.
app.sinusoidLine = plot(app.UIAxes,time,y);
Store the object as property (i.e. app.sinusoidLine).
Then change the XData and YData properties of the line in your callback function.
app.sinusoidLine.XData = time;
app.sinusoidLine.YData = y;
