Details:

Using   h_b(ii)=uicontrol(... in a loop

and get(h_b,'value') in the callback function will not given a result which
button was hit.

In Matlab the hselected cellarray of h_b(ii) will be marked with 1, the others
are zero.

See added code. 

Main

%---------------------
function ui_test

global h_b

clc;
close all
scrsz = get(0,'ScreenSize');
src_y=scrsz(4);
blatt=900;
src_p=src_y-blatt-50;
wide=1100;
pos=blatt-10;
dum=ver;
b=dum.Name;
if strcmpi(b,'octave')
    figure(1,'Units','pixels','Position',[20 src_p wide
blatt],'MenuBar','none','Color',[0.8 0.8 0.8],...
    'Name','UI_test','resize','off')
else
    figure(1)
    set(1,'Units','pixels','Position',[20 src_p wide
blatt],'MenuBar','none','Color',[0.8 0.8 0.8],...
    'Name','UI_test','resize','off')
end

for ii=1:4 
    h_b(ii)=uicontrol('Style','pushbutton','Position',[10 pos-ii*30 30
30],'string'...
        ,num2str(ii),'FontSize',10,'Callback','test');
end 
%--------------------

Callback function for test

function test()
global h_b

get(h_b,'value')


will show:
>> ans =
{
  [1,1] = 0
  [2,1] = 0
  [3,1] = 0
  [4,1] = 0
}


whereas the same call in Matlab will show

ans =

  4×1 cell array

    {[0]}
    {[0]}
    {[1]}
    {[0]}

if 3rd button was selected
