Citrus quality detection and grading system based on MATLAB GUI

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