Dear MATLAB users,

I hope you can help me in suggesting the suitable code to make the GUI works. This is example how I would like the slider to function:

Given two inputs A and B. I write mathematical equation ex: A+B=C.

And I would like the slider to move automatically based on the value of C. Is it possible?

Yes, you could make two Edit Field (Numeric) components, one for A and the other representing B.

You can add the following callbacks for the Edit Fields:

        % Value changed function: EditField
        function EditFieldValueChanged(app, event)
            app.Slider.Value = app.EditField.Value+app.EditField2.Value;
        end
        
        % Value changed function: EditField2
        function EditFieldValue2Changed(app, event)
            app.Slider.Value = app.EditField.Value+app.EditField2.Value;
        end
