Files with the .p extension are pseudo-code files that have been parsed and obfuscated by MATLAB. Over the years, the search term has grown popular among developers, researchers, and reverse engineers. This phrase usually refers to compressed archives circulating online that claim to contain tools for decrypting or decompiling these protected files back into readable .m source code.

This is the most critical area for any user to understand. Reverse engineering or decompiling P-code occupies a gray area, but one heavily tilted towards the side of the code's original owner.
