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. Choose "GUI allows only one
% instance to run (singleton)".
