% singleton*. %

% H = MULTIRATE returns the handle to a new MULTIRATE or the handle to % the existing singleton*.

% MULTIRATE('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in MULTIRATE.M with the given input arguments. %

% MULTIRATE('Property','Value',...) creates a new MULTIRATE or raises the % existing singleton*. Starting from the left, property value pairs are

% applied to the GUI before Multirate_OpeningFunction gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to Multirate_OpeningFcn via varargin. %

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one % instance to run (singleton)".
