I'm trying to create a random signal generator with stem plot in Matlab App Designer, and when I click the 'Generate' Button - nothing happens. Below is the code I added in the generated code from the app designer.
methods (Access = private)
%generate button is pushed
function GenerateButtonPushed(app, event)
amplitude = app.AmplitudeEditField.Value;
samples = app.SamplesEditField.Value;
n_range1 = app.nRange1EditField.Value;
n_range2 = app.nRange2EditField.Value;
n_range = n_range1:n_range2;
xn = amplitude .* sin(2*pi*randn(1,samples));
%plot random signal
stem(n_range,xn, 'parent', app.UIAxes)
When I ran this block of code in a live script in Matlab. It worked, but the graph won't show when I run it with the GUI.

Edit: Both of these functions work, actually, the error is in writing a callback manually without assigning it to the component. In App Designer, click the right mouse button on the button component and go to callbacks and add one. Then you paste the body of your code in it.
