trying to make a switch case for the dropdown with options: sine,cosine,square, triangular, to plot the right wave whenever chosen, this only plots sine wave, what's wrong?

value = app.SignalGeneratorDropDown.Value;

app.t=0:0.01:1

app.A= app.AmplitudeEditField.Value;

app.f= app.FrequencyEditField.Value;

app.y=app.A*sin(2*pi*app.f*app.t);

switch value

case "Sine"

app.y=app.A*sin(2*pi*app.f*app.t);

case "Square"

app.y=app.A*Square(2*pi*app.f*app.t);

case "Cosine"

app.y=app.A*cos(2*pi*app.f*app.t);

case "Triangular"

app.y=app.A*sawtooth(2*pi*app.f*app.t);

end

plot(app.UIAxes,app.t,app.y);

xlabel(app.UIAxes,"Time")

ylabel(app.UIAxes,"Amplitude")

title(app.UIAxes,"waveform")

Hi Rana,

I have tried to recreate the issue at my end and the code seems to run correctly, with sin, cos, square and sawtooth waveforms getting plotted onto UIAxes according to dropdown input. Please ensure you have the above code inside DropDown 'ValueChangedFcn' function callback. If the issue still persists, upload your file and we shall have a look at it.

Regards.
