You can't convert it.

You could ask the author for the *.m source file. That is the only way you can get the original *.m file.

pcode is encrypted using AES encryption, using a key only known to Mathworks, so only Mathworks could convert it back. Need to get mfile from the original author

CTF files are encrypted, but as far as I have heard, pcode are merely binary with an undocumented format.
