Isaac - you are obtaing the angle as

angle = app.Angle;

where presumably Angle is the handle to the matlab.ui.control.NumericEditField and so is not the angle itself. You may need to do someting more like

angle = app.Angle.Value;

to get the value of the angle. (I'm assuming that since this is a NumericEditField, you don't have to convert the above from a string to a number.)

Note that if the above works, you will need to do the same for the initial population and initial velocity.

You need to access the value stored in your edit fields:

            a = app.EditField.Value;
            b = app.EditField2.Value;
           c= a + b;
            app.EditField3.Value = c;

MATLAB: App designer 3d in GUI – Rotate3d

I was able to do this using the following to control the UIAxes that I added to my AppDesigner app.

rotate3d(app.UIAxes,'on');

Note that this will turn the rotation permanently on, so I recommend having a toggle button to switch it on and off. Otherwise, every time you mouse over the axes, it will try to rotate.

Based on this documentation, however, interactivity with plots is not officially supported, so you may see some improvements/changes to this in future releases. https://www.mathworks.com/help/matlab/creating_guis/graphics-support-in-app-designer.html
