MATLAB - Starting a function automatically after GUI loads

Question

I have a Matlab application that has GUI in it. I am now trying to automate some operations and i need to call a function right after the GUI loads without any human in the loop. (Basically simulating human button clicks...)

I have tried calling the wanted function from "_OpeningFcn" and from "_OutputFcn" with no success.

I also tried to follow this link, yet it doesn't work as well :( http://www.mathworks.com/matlabcentral/answers/161545-call-callback-without-mmouse

Any other ideas to how i can invoke a function programmaticly after GUI is fully loaded?

THanks!

Edit1: AS i understood, if i want to call the function then i should bot it in "EnergyData_OutputFcn". so, here is what it looks like:

function varargout = EnergyData_OutputFcn(hObject, eventdata, handles)
% varargout  cell array for returning output args (see VARARGOUT);
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Get default command line output from handles structure

hGuiFig = findobj('Tag','btnReportGeneration');
EnergyData('btnReportGeneration_Callback',handles.btnReportGeneration,[],handles);
varargout{1} = handles.output;

the thing is that this function is called recursively (i can see it when debugging) and i eventually get this error message:

Maximum recursion limit of 500 reached. Use set(0,'RecursionLimit',N)
to change the limit.  Be aware that exceeding your available stack space
can
crash MATLAB and/or your computer.

Error in genvarname>isCellString

That brings me to the question that assuming the method described in the post i attached in link above is the correct way, Where do i place this code? (I couldn't even find it in the example files he attached to the post...)

THANKS FOR THE HELP!

How exactly did you try what's posted in the link? It worked quite well for me. Can you post your codes? — user3667217, Sep 17 '15 at 22:12
THanksThese are the two lines i added: hGuiFig = findobj('Tag','btnReportGeneration') ; EnergyData('btnReportGeneration_Callback',handles.btnReportGeneration,[],handles) — Eitan Vesely, Sep 18 '15 at 06:07
Do you mind putting these codes in your original post and describe what kind of error you encountered after you tried calling the GUI? — user3667217, Sep 18 '15 at 07:05
OK, I now got it. im calling it from an external script, WOrking like a charm :) — Eitan Vesely, Sep 19 '15 at 09:21

When automatically created with guide, you should have this part in your GUI code ? (you can create a simple GUI with guide and figure out where does it go otherwise)

% Begin initialization code - DO NOT EDIT
gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                   'gui_Singleton',  gui_Singleton, ...
                   'gui_OpeningFcn', @V2Gsim_gui_OpeningFcn, ...
                   'gui_OutputFcn',  @V2Gsim_gui_OutputFcn, ...
                   'gui_LayoutFcn',  [] , ...
                   'gui_Callback',   []);
if nargin && ischar(varargin{1})
    gui_State.gui_Callback = str2func(varargin{1});
end

if nargout
    [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
else
    gui_mainfcn(gui_State, varargin{:});
end
% End initialization code - DO NOT EDIT

Then calling on (in my case)

function V2Gsim_gui_OpeningFcn(hObject, eventdata, handles, varargin)

You can launch any function even before the GUI is opened.

How does this answer the question? You've just copy/pasted the pregenerated GUIDE code. — sco1, Sep 18 '15 at 12:20
