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