- Compile your source code files using the MATLAB Compiler to produce a standalone application.

MATLAB does not support converting live scripts to P-code files. It is not recommended that you P-code files to protect your intellectual property. While the content in a.p file is difficult to understand, it should not be considered secure. When MATLAB P-codes a file, the file is obfuscated not encrypted.

- Convert some or all of your source code files to a content-obscured form called a P-code file (from its.p file extension), and distribute your application code in this format.

If we open that file with the help of notepad or WordPad then we canвЂ™t get anything from. Matlab has a standard encryption key using that key Matlab will convert.m to.p file. We can convert important functions from.m to protected files. You have to decrypt the file at first and write. You decrypt its pixel values using AES, and you get nonsense -because the ciphertext you are decrypting is not the result of an AES encryption, it's the result of an AES encryption plus the errors introduced by JPEG compression. As per MATLAB it is not possible to reverse engineer it back to m file. So it may be a form of byte code with may be a weak encryption. The size of P-code is less than the m-code file size. The original.m file or folder can be anywhere on the search path. MATLABВ® creates the P-files in the current folder. Because currently the P-code algorithm is not documented, the best reliable assumption is that a weak to very weak encryption method is applied, such that it is more a kind of obfuscation. But this can be an effect of the file size.

For large M-files with 10'000th of lines opening the P-file the first time is faster than for the M-file. Quoting the manual: You invoke the resulting P-code file in the same way you invoke the MATLAB.m source file from which it was. If by 'open' you mean run - then certainly yes. 'p' in pcode is for 'protected' - its main design goal is deploying a functional component while protecting its source. If by 'open' you mean edit - then certainly not.
