Good catch, Bruno. I got sidetracked by the "undefined b".
But to be more correct, you can use a variable in imread(), but it needs to be a variable that contains a string. For example,
F = 'C:\Users\Romesha\Desktop\eye.jpg';
im = imread(F);

  • * *Error in @(hObject,eventdata)gui('PB2_Callback',hObject,eventdata,guidata(hObject))
Error while evaluating uicontrol Callback* * *
