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