Matlab GUI is not running

I try to run my GUI ( it works perfectly recently) and it's not running. I am pressing green arrow and nothing open. What might cause these ?

[per isakson]

Any error message?

Any other hint from Matlab?

Different working folder?

[Jonasz]

Nothing. No error , I change nothing. GUI is not working but function inside GUI which I put there is running from command window. GUIDE is opened but when I pressed green arrow to start run the program nothing happen also I tired to open *.fig file and still the same.

[Jonasz]

My code :

function varargout = program(varargin)
% PROGRAM MATLAB code for program.fig
%      PROGRAM, by itself, creates a new PROGRAM or raises the existing
%      singleton*.
%
%      H = PROGRAM returns the handle to a new PROGRAM or the handle to
%      the existing singleton*.
%
%      PROGRAM('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in PROGRAM.M with the given input arguments.
%
%      PROGRAM('Property','Value',...) creates a new PROGRAM or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before program_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to program_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

I also try to create new GUI and works fine so it's something wrong with these code.

[per isakson]

I guess the problem is with program.fig. Errors in m-code causes error messages.

Try

    dbstop if error

[Jonasz]

Where I should put this command?

[per isakson]

In the command window set

    >> dbstop if error

and inspect the Workspace window when the break occurs
