how can I use a push button callback function to store a data that i get from a uitable into a popupmenu , so that the data (a string) will remain there even i close the gui

I have created a uitable, I want the user to be able to modify data of columns then the data of the first column will be saved and sent to the popupmenu using a pushbutton. this is the code of the tabe: f = figure('Position',[200 200 400 150]); dat ={'a',6.125, 456.3457;... 'b',6.75, 510.2342;... 'c', 7, 658.2;} cnames = {'id_ellipsoïde','demi_grand_axe','excentricite'}; rnames = {1:3}; t = uitable1('Parent',f,'Data',dat,'ColumnName',cnames,... 'RowName',rnames,'Position',[20 20 360 100]);

the code to modify a clumns is:

data=get(handles.uitable1,’data’.) data(end+1, :)=0 ; set(handles.uitable1,’data’,data);

and this is was I wrote (following the above code) trying to definitively store the data to the popupmenu that should remain there even after closing the GUI

b=get(handles.popupmenu1,'string'); c=data(end,1); b(end+1,1)=c; set(handles.popupmenu1,'string',d);

The data does not remain in the popupmenu

Thank you
