If you have a .wav file i think this will work. First load your file:
[y f]=audioread('yourMusicFile.wav');
Then play audio with:
sound(pl);
Stop sound with:
clear playsnd;

when me use this code your recommended:
[y f]=audioread('21.mp3');
handles.player = audioplayer(y,f);
play(player);
then error show:
Undefined function or variable 'player'.
Error in Face_Detection_And_Recognition>Face_Detection_And_Recognition_OutputFcn (line 100)
play(player);

audioplayer can play without play blocking (so your other processes and continue).

When you play a song with sound, it blocks audioplayer does not so you can have your code running.
Read the example in the doc linked or at:
doc audioplayer
