recObj = audiorecorder;
disp('Start speaking.')
recordblocking(recObj, 5);
disp('End of Recording.');
y = getaudiodata(recObj);
figure
plot(y);
title('Hello World!')
audiowrite(recObj, 1, 22050); 
play(recObj);

this what i was able to reach in the code but i keep getting a error like this

Error in audiowrite (line 111)

props = parseInputs(filename, y, Fs, varargin);

Error in Test1 (line 9)

audiowrite(recObj, 1, 22050);

you have to tell audiowrite a file name. You do not have to tell it the number of channels. You have to pass the data to be written to it, which is y, not the recording object

thank you so much, it is working now but how can i save the .wav file or where can i find it?

If you do not provide a directory as part of the file name then it will be saved in your current directory. You may wish to provide fully qualified file name.
