MATLAB: App Designer Radio Button

app designerradio button

Hi! I currently have a problem with a radio button I am using for app designer. The purpose of my radio button is to select one of these three equations to be calculated based on what the user needs. The problem occurs when the app is closed then reopened, the "Linear" button is automatically selected; however, the code does not count this as actually selecting the linear button, and it will perform the calculations based on what button was selected just before the app was closed. So if you want to use the linear button on startup, you have to unselect it then selected it again. Not very user friendly. Any way to fix this? Thanks
Here is my code that controls the radio button then calculates the notch response based on the selection.
if Y == 1
NotchResponse = (app.EquationsSlopeEditField.Value).*(Depth)+ app.EquationsYInterceptEditField.Value;
elseif Y == 2
NotchResponse = (app.EquationsSlopeEditField.Value).*(log(Depth))+ app.EquationsYInterceptEditField.Value;
elseif Y == 3
NotchResponse = (app.EquationsSlopeEditField.Value).*((Depth).^(app.ExponentEditField.Value));
end

Hi Jonathan,
A simple solution to this problem is to select the Linear button in the startup function
If you are not able to find startup function then you can add it from callbacks.
I highly encourage you to use startup function for the initialization of everything, so the app starts without any glitches.
Let me know if this helped you
