-in matlab appdesigner i want a edit field to read in multiple double values and confirm with enter in matlab in matlab

To create an edit field in MATLAB App Designer that can read in multiple double values and confirm with the enter key, you can use the following steps:

1. Open App Designer by typing appdesigner in the MATLAB command window.
2. Create a new App or open an existing one.
3. Drag and drop an "Edit Field" component from the "Common" section of the "Component Library" on the left-hand side of the App Designer window.
4. Customize the properties of the Edit Field component as needed. For example, you can set the "Tag" property to a unique identifier.
5. Right-click on the Edit Field and select "View Callbacks" -> "KeyPressedFcn" from the context menu.
6. In the MATLAB code editor that opens, write the code to handle the Enter key press event. You can use the following example code:

main.m
function EditFieldKeyPressed(app, event)
    if strcmp(event.Key, 'return')
        % Get the value entered in the Edit Field
        enteredValue = str2double(app.EditField.Value);
        
        % Verify if the entered value is a valid double number
        if ~isnan(enteredValue)
            % Process the entered value
            disp(['Entered value: ', num2str(enteredValue)]);
        else
            % Display an error message if the entered value is not a valid double
            disp('Invalid input!');
        end
    end
end

Make sure to replace EditField with the actual Tag of your Edit Field component. You can also modify the code inside the if ~isnan(enteredValue) block to suit your specific needs.

7. Save the changes and run the App to test the Edit Field behavior.

Now, when the user enters a value into the Edit Field and presses the Enter key, the entered value will be processed according to your code.
