Hello, I am working on a GUI using two buttons where the enhancement operations perfromed on an image can be changed. Once I select the required operation; I have an another drop down gives options in relation to the first selection. My questions is
- It looks like by default the first button is always pressed. So when am running if condition to check whether the first button is selected or not; some how the code within the if not executing; it is only executing when the value is changed (means when option changed from one radio button to the other and vice versa)
How can i access the initial value or default value of radio button selection.
Thanks.

What is your trigger? Do you want the app to open with the linear stretching result already displayed? If so, place the following at the bottom of your startupFcn callback.
MethodButtonGroupSelectionChanged(app, app.MethodButtonGroup)

- Create property that takes Method and Contrast level values.
- Create a callback for button group (method and image enhancement operation) - see this property (app.ImageEnhancementOperationButtonGroup.SelectedObject.Text)
- Create a callback that sends contrast dropdown value to property.
- Initialise starting values in startupFcn, for each component.
You read your image twice, save it in a property.
