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