Hi,

your else if (in C code) conditions are badly written -> elseif in matlab code.

and the conditions are not conditions. you need to use == instead of =.

something like

if obj==L;
    [y,fs]=wavread('tl.wav');
    player=audioplayer(y,fs);
    play(player)
elseif  obj==R;
    [y,fs]=wavread('tr.wav');
    player=audioplayer(y,fs);
    play(player)
elseif obj==F;
    [y,fs]=wavread('mf.wav');
    player=audioplayer(y,fs);
    play(player)
elseif obj==B;
    [y,fs]=wavread('mb.wav');
    player=audioplayer(y,fs);
    play(player)
else
    [y,fs]=wavread('s.wav');
    player=audioplayer(y,fs);
    play(player)
end
