Music retrieval based on MATLAB music retrieval system

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