I used matlab online , wrote the same code and got the following message:
No audio input device found on this system.
What dos that mean? What should I do?

Hi,
As a first step in troubleshooting this issue, I would suggest updating the software with latest release as it fixes most of the "Device Error" related issues. And, please make sure you restart MATLAB after plugging in any new devices because MATLAB does not automatically refresh the list of devices.
If the problem still persists then please share the output of the "audiodevinfo" command by saving it to a .MAT file. You can do this by entering the following commands at the command window:
>> info = audiodevinfo;
>> save('audioInfo.mat', 'info');
Ensure that the required device is present in the 'output' field of the struct.
