Hi everybody . Just shared my code below . I have done the Decoding part , I have no idea how can I do the Encoding part again anyone knows ?

Also how can I make it more like user interface . I want user to see the decoding via buttons or something like that . Any idea ?

The code you posted in https://www.mathworks.com/matlabcentral/answers/437725-dtmf-decoder-with-touch-tones does the encoding already. The part where it uses sin synthesis to create the y values is DTMF encoding.
