In such cases, a Matlab P-code decoder is necessary to extract the contents of the P-code file.
: The decompressed stream contains numeric tokens that represent MATLAB keywords, operators, and built‑in functions. A token table (reverse‑engineered from MATLAB’s parser) maps these tokens to their human‑readable equivalents. If you share with third parties, their policies apply

If you are trying to share code while protecting your own work, you might find the PCode Release Tool on MATLAB Central useful for managing your distributions safely. pcode - Create content-obscured, executable files - MATLAB : This denotes a 7-Zip compressed archive file,
The confusion is understandable, as some sources describe the process using terms like "encryption." For example, when MATLAB Compiler deploys applications, it does employ AES-256 encryption for the code files within the archive—but that applies to compiled executables and deployed archives, not to the standard pcode command's output. The base pcode function produces an obfuscated bytecode format, not a cryptographically secured ciphertext.
Searching for or utilizing tools like "Matlab P-code Decoder.7z" introduces substantial security vulnerabilities to your workstation and network, often yielding non-functional software or malicious threats. To protect intellectual property effectively, transition from simple file obfuscation to robust compilation and deployment frameworks provided within the official MATLAB ecosystem.
The technical reality is clear: MATLAB P‑code is . It can be decoded, and multiple tools exist to do so. But the ethical and legal boundaries are equally clear: respect intellectual property, honor software licenses, and use these tools only where you have the right to do so.
