It is indeed a 2x1 string at first but if you edit the content of the uicontrol (or just type enter to validate it), it returns a string, e.g. I get this if I replace 'a|b' with 'c<ENTER>d'

ans = c

it looks like get(H,'String') returns a 2x1 cell, so it is just not displaying the same as matlab does

My main issue is actually with an 'edit' uicontrol:

H=uicontrol(F,'style','edit','Max',2,'string',{'a','b'},'units','normalized','Position',[0.05 0.05 0.9 0.9]);
% type return in the figure

i.e. a multiline text edit is returned as a pipe-separated string instead of a cell array.

Related in matlab [1] : If you specify a cell array for a check box, push button, radio button, or toggle button, then MATLAB displays only the first element in the cell array.

Currently octave will display a | b for the button etc as well.

F = figure;
uicontrol(F,'style','text','string',{'a','b'},'units','normalized','Position',[0.05 0.05 0.9 0.9]);

Octave displays:


while MATLAB displays:
