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