when I run the code, I get the following error. I have attached the m file and the fig file as well. I did not write these codes but I need to debug it. Do you have any ideas what goes wrong?

Undefined function or variable 'Angle_B2_CreateFcn'.

Error in gui_mainfcn (line 95)

feval(varargin{:});

Error in pic_display (line 42)

gui_mainfcn(gui_State, varargin{:});

Error in

matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)pic_display('Angle_B2_CreateFcn',hObject,eventdata,guidata(hObject))

Error using Meary's Angle

Error: Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters,

or other syntax error. To construct matrices, use brackets instead of parentheses.

Undefined function or variable 'Angle_B2_DeleteFcn'.

Error in gui_mainfcn (line 95)

feval(varargin{:});

Error in pic_display (line 42)

gui_mainfcn(gui_State, varargin{:});

Error in

matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)pic_display('Angle_B2_DeleteFcn',hObject,eventdata,guidata(hObject))

Error using closereq (line 18)

Error while evaluating UIControl DeleteFcn.

Since you didn't write it, I can say this code is bad. When I try to run it, it hits the line

X_AP = evalin('base','X_AP');

and then throws an error, followed by a bunch of similar errors where it tried to read in X_AP from the base workspace. I don't think most good MATLAB programmers would use evalin(). To get this code to work, you'll have to supply us with the code that loaded all the various X_* variables into the base workspace.

it can be anything, the goal is to measure some angles on those images and save the number into that Scores file.

I figured that part out. There was no CreateFcn for that variable, so I created that. But now I have another error when I push the Save bottun. I went over the code, there is not even one kind of this at all.
