The ERROR : Undefined function or variable 'untitled1_OutputFcn'.
Error in gui_mainfcn (line 264)
feval(gui_State.gui_OutputFcn, gui_hFigure, [], gui_Handles);
Error in untitled1 (line 42)
gui_mainfcn(gui_State, varargin{:});
This is my code
function varargout = untitled1(varargin)
% UNTITLED1 MATLAB code for untitled1.fig
% UNTITLED1, by itself, creates a new UNTITLED1 or raises the existing
% singleton*.
%
% H = UNTITLED1 returns the handle to a new UNTITLED1 or the handle to
% the existing singleton*.
%
% UNTITLED1('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in UNTITLED1.M with the given input arguments.
%
% UNTITLED1('Property','Value',...) creates a new UNTITLED1 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before untitled1_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to untitled1_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
