Hi. I have two distinct files, myguide.fig (and its corresponding mygui.m) which contains the definition of an uitabgroup and the file caract.fig (and its corresponding caract.m) which contains a panel. I call the file caract.m from the file myguide.m and obtain the handle of the panel. Then I change the Parent property of the panel to assign it to one of the tabs of the uitabgroup. I only achieve that this works (setting the Visibility Property of caract.fig off) the first time I run myguide. If I try to run it a second time, I get the error message “Invalid handle object” for the handle of the panel returned. I do not understand what is happening.
