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