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