function varargout = guipic(varargin) % GUIPIC MATLAB code for guipic.fig % GUIPIC, by itself, creates a new GUIPIC or raises the existing % singleton*. % % H = GUIPIC returns the handle to a new GUIPIC or the handle to % the existing singleton*. % % GUIPIC('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in GUIPIC.M with the given input arguments. % % GUIPIC('Property','Value',...) creates a new GUIPIC or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before guipic_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to guipic_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one % instance to run (singleton)". % % See also: GUIDE, GUIDATA, GUIHANDLES % Edit the above text to modify the response to help guipic % Last Modified by GUIDE v2.5 13-Mar-2021 17:27:58 % Begin initialization code - DO NOT EDIT gui_Singleton = 1; gui_State = struct('gui_Name', mfilename, ...
