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