The size of P-code is less than the m-code file size. So it may be a form of byte code with may be a weak encryption. As per MATLAB it is not possible to reverse engineer it back to m file. Decrypt P File Matlab Code 4,2/5 7850 votes No, there is no decoding method for P-coded functions. You can use the debugger to step through the code line by line.

I tried the Boomerang software, it extracts the project m-files and figures. The figures are ok and the MATLAB can show them. Neobook serial. But when I open the m. The size of P-code is less than the m-code file size. So it may be a form of byte code with may be a weak encryption. As per MATLAB it is not possible to reverse engineer it back to m file.

Protect Your Source Code

Although MATLAB^® source code (.m) is executable by itself, the contents of MATLAB source files are easily accessed, revealing design and implementation details. If you do not want to distribute your proprietary application code in this format, you can use one of these options instead:

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

  MATLAB does not support converting live scripts or live functions to P-code files.

• Compile into binary format — Compile your source code files using the MATLAB Compiler to produce a standalone application. Distribute the latter to end users of your application.

Building a Content Obscured Format with P-Code

A P-code file behaves the same as the MATLAB source from which it was produced. The P-code file also runs at the same speed as the source file. P-code files are purposely obfuscated. They are not encrypted. While the content in a .p file is difficult to understand, it should not be considered secure. It is not recommended that you P-code files to protect your intellectual property.

Note

Because users of P-code files cannot view the MATLAB code, consider providing diagnostics to enable a user to proceed in the event of an error.

Building the P-Code File

To generate a P-code file, enter the following command in the MATLAB Command Window:

The command produces the files, file1.p, file2.p, and so on. To convert all.m source files residing in your current folder to P-code files, use the command:

See the pcode function reference page for a description of all syntaxes for generating P-code files.

Invoking the P-Code File

You invoke the resulting P-code file in the same way you invoke the MATLAB .m source file from which it was derived. For example, to invoke file myfun.p, type

To invoke script myscript.p, type

When you call a P-code file, MATLAB gives it execution precedence over its corresponding .m source file. This is true even if you happen to change the source code at some point after generating the P-code file. Remember to remove the .m source file before distributing your code.

Running Older P-Code Files on Later Versions of MATLAB

P-code files are designed to be independent of the release under which they were created and the release in which they are used (backward and forward compatibility). New and deprecated MATLAB features can be a problem, but it is the same problem that would exist if you used the original MATLAB input file. To fix errors of this kind in a P-code file, fix the corresponding MATLAB input file and create a new P-code file.

P-code files built using MATLAB Version 7.4 and earlier have a different format than those built with more recent versions of MATLAB. These older P-code files do not run in MATLAB 8.6 (R2015b) or later. Rebuild any P-code files that were built with MATLAB 7.4 or earlier using a more recent version of MATLAB, and then redistribute them as necessary.

Building a Standalone Executable

Another way to protect your source code is to build it into a standalone executable and distribute the executable, along with any other necessary files, to external customers. You must have the MATLAB Compiler™ and a supported C or C++ compiler installed to prepare files for deployment. The end user, however, does not need MATLAB.

To build a standalone application for your MATLAB application, develop and debug your application following the usual procedure for MATLAB program files. Then, generate the executable file or files following the instructions in Create Standalone Application from MATLAB (MATLAB Compiler).

P files are used with the Pascal programing source code using the Applause software application. P files contain picture files created by Pascal. The Python programming language also utilizes this file extension to store Python module files which are not yet in the byte stream format. MATLAB uses the extension to contain binary-runtime files within the application. Pascal and the P file extension were published in 1970 as an efficient option for structured programming and data structuring. There are many free compiler programs of Pascal programming coding. Many of the changes and development of Pascal occurred in Zurich.

Technical details of P files

Pascal was intended to be efficient (in relation to compilation speed and generated code) using the structured programming methods. Pascal is rooted in ALGOL 60 but improved the concept by enabling the ability to define datatypes, and building dynamic and recursive data structures. Strong typing is utilized; meaning specific types of data cannot be interpreted or converted to other types easily. A porting kit was created to include a compiler to generate coding for a “virtual” stack machine, referred to Pascal-P1 (up to Pascal-P4). Eventually, Pascal-P5 was created, which brought in ISO 7185 compatibility. Data types include integers, real, Boolean, char, and string.
