MATLAB is a popular programming language and environment used extensively in various fields, including engineering, physics, and data analysis. One of its key features is the ability to create and execute P-code files, which are platform-independent, compiled MATLAB files. However, when working with P-code files, it's essential to have a reliable decoder to extract and analyze their contents. In this write-up, we'll explore the MATLAB P-Code Decoder and its connection to 7-Zip, a widely-used file archiver.
