Can someone figure out whats wrong with my code?

I'm trying to develope a code for my GUI,but when I try to run this error pop out

*Field assignment to a non-structure array object.

Error in PROJECT_2>btnRUN_Callback (line 126) Out(1).Loc='(0)Normal ';

Error in gui_mainfcn (line 95) feval(varargin{:});

Error in PROJECT_2 (line 42) gui_mainfcn(gui_State, varargin{:});

Error in matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)PROJECT_2('btnRUN_Callback',hObject,eventdata,guidata(hObject)) Error while evaluating UIControl Callback.*

Attached files are my code,txt format and GUI program,thanks!

You are a call to a function like this:

[Out]=UDF_Uncontrol(E0,y0,yc2,h,q2);

which returns an "Out" variable that is not a struct array apparently. Then you try to modify the same variable immediately after that call as if it is a struct:

Out(1).Loc='(0)Normal

Either make sure Out from the first function is a struct array, or rename the second Out something else like OutX.

unfortunately it doesn't work for renaming the second Out.
