function varargout = importpicture(varargin)
% IMPORTPICTURE MATLAB code for importpicture.fig
% IMPORTPICTURE, by itself, creates a new IMPORTPICTURE or raises the existing
% singleton*.
%
% H = IMPORTPICTURE returns the handle to a new IMPORTPICTURE or the handle to
% the existing singleton*.
%
% IMPORTPICTURE('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in IMPORTPICTURE.M with the given input arguments.
%
% IMPORTPICTURE('Property','Value',...) creates a new IMPORTPICTURE or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before importpicture_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to importpicture_OpeningFcn via varargin.

% instance to run (singleton)".
