Dear all,

I have this code:

    function varargout = GUI_projekt1(varargin)
    % GUI_PROJEKT1 MATLAB code for GUI_projekt1.fig
    %      GUI_PROJEKT1, by itself, creates a new GUI_PROJEKT1 or raises the existing
    %      singleton*.
    %
    %      H = GUI_PROJEKT1 returns the handle to a new GUI_PROJEKT1 or the handle to
    %      the existing singleton*.
    %
    %      GUI_PROJEKT1('CALLBACK',hObject,eventData,handles,...) calls the local
    %      function named CALLBACK in GUI_PROJEKT1.M with the given input arguments.
    %
    %      GUI_PROJEKT1('Property','Value',...) creates a new GUI_PROJEKT1 or raises the
    %      existing singleton*.  Starting from the left, property value pairs are
    %      applied to the GUI before GUI_projekt1_OpeningFcn gets called.  An
    %      unrecognized property name or invalid value makes property application
    %      stop.  All inputs are passed to GUI_projekt1_OpeningFcn via varargin.
    %
    %      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
    %      instance to run (singleton)".
