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