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