Dear all, i have created a GUI without GUIDE and i am wondering how it's possible to call the OpeningFcn function like in GUIs created with GUIDE.

As joseph said - you dont need to.
One way around it is to create your figure with visible set to off - call your own OpeningFcn - then set visible to on!

Do you need to? whatever you're using to create the GUI (not with GUIDE) is the OpeningFcn portion.

well it looks like you're compiling it into a standalone exe? then i do not think putting it in the openingfcn equivalent is going to help as its taking 2min for matlab runtime to get everything straight before showing you anything.
http://www.mathworks.com/matlabcentral/answers/92901-how-can-i-show-a-splash-screen-when-the-mcr-is-loading-in-windows-standalone-application-mode is a thread i found that maybe relevant.
If you're not compiling to an executable then here is an example with the little details on why it takes 2 min (actual processing occurring or just displaying a simple GUI?). (come code or description of your startup sequence would have been nice):
function SplashScreen_Main()
fig_hand = figure; %figure handles
fig_size = get(fig_hand ,'Position');
I = imread('logo.tif');
AXES = axes;
imagesc(I),colormap(gray),set(AXES,'Position',[0 0 1 1])
set(fig_hand,'menubar','none');
Process_2minStartup(10)
YPos_offset=-65; %offset in y
%loop to generate popups.
for i=1:5
Type(i)=uicontrol('Style', 'popup',...
'String', '|1|2|3|4|5',...
'Position', [20 340+(i-1)*YPos_offset 100 50],'tag',['TYPE' num2str(i)]);
end
%setting some to enable off;
set(Type(1),'Enable','off');
set(Type(3),'Enable','off');
%disp(Type) %my debuging
%generate pushbutton.
Pbutton=uicontrol('Style', 'pushbutton',...
'String', 'check',...
'Position', [220 340 100 20],...
'Callback', {@check, fig_hand});
delete(AXES)
function Process_2minStartup(seconds)
pause(seconds)
function check(~,~,fig_hand)
TYPE=findobj(fig_hand,'Style','popup') %this is just to see if the popup numbers match what i have above for Type.
popup_tag = get(TYPE,'tag'); %get the tags
popup_enabled = get(TYPE,'Enable'); %get enabled
popup_stuff = get(TYPE,'String'); %get whats inside the pop up boxes
popup_select = get(TYPE,'Value'); %get which item was selected
for ind = 1:length(TYPE)
if strcmp(popup_enabled{ind},'on'); %check which popups are enabled
if strcmp(popup_stuff{ind}(popup_select{ind}),' ') %check if empty
fprintf(2, 'Problem: Empty string in: %s\n', popup_tag{ind});
else
fprintf(1,'Good: Valid string in: %s is %s\n', popup_tag{ind}, popup_stuff{ind}(popup_select{ind}));
end
else
fprintf(1,'Enable Off for Popup: %s\n', popup_tag{ind});
end
end
Pardon the not relevant code but to save some time i used an example i gave earlier today. So depending on whats taking the 2 min move the splash screen above.

what version of matlab are you using? In R2014a you can specify a splashscreen which Matlab will display while the MCR loads (which is most likely to be whats taking the majority of the time).
