I do simple App Designer to Circle/Sphere Calculations but I have error her
app.radius = app.EntertheradiusEditField.Value;
diameter = 2*app.radius;
[[[ app.ThediameterisEditField.Value = diameter;]]]
app.AreaEditField.Value=pi*app.radius^2;
app.CircumferenceEditField.Value =2*pi*app.radius;
app.VolumEditField.Value=(4/3)*pi*app.radius^3;
app.SurfaceEditField.Value=4*pi*app.radius^2;
Error using matlab.ui.control.EditField/set.Value (line 98)
'Value' must be a character vector or a string scalar.

Hello,
The component EDITED app.EntertheradiusEditField.Value is probably a Text Field, which accepts only characters/array, replace it with the numeric field component.
I would suggest you to work through the example applications in App Designer and you'll understand how things work clearly.

Try this:
app.ThediameterisEditField.String = num2str(diameter);
Same for the other edit fields. The contents of the edit text box are the "String" property of the control not the "Value" property.

Property Value is same for both styles of edit field component.
