function play_Callback(hObject, eventdata, handles)
% hObject handle to play (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
global stop file_name C;
stop=1;
equalizer_play();
function equalizer_play()
global stop file_name C;
[x,Fs]= audioread(file_name);
[a,b]=coef();
l_bucata=2*Fs;
Nb=round(length(x)/l_bucata);
y=0;
for i=1:floor(Nb)
bucata=x((i-1)*l_bucata+1:i*l_bucata);
for k=1:5
y=y+filter(10^(C(k)/20)*b{k},a{k},bucata);
if(stop==0)
break;
end
end
wavplay(y,Fs,'async');
y=0;
if(stop==0)
break;
end
end

Undefined function or variable 'wavplay'.
Error in MyEqualizer>equalizer_play (line 507)
wavplay(y,Fs,'async');
Error in MyEqualizer>play_Callback (line 490)
equalizer_play();
Error in gui_mainfcn (line 95)

Error while evaluating UIControl Callback.
What is the solution for such error ?

Hassan - is code referencing wavplay from the File Exchange (the inputs seem to match)? If so, have you downloaded the code and added it to the MATLAB Search Path?

R2012a was the last release that had wavplay().
