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