10/25/2019 Decrypt P File Matlab Function
Hi everyone, I am taking a 'Matlab for engineers' class and I have been using Octave instead so for with great results. Thanks for the good work.
The only time I have to go into Matlab ( a friends comp or library) is when the Professor gives us a.p file so that we can test our functions. Now I just check the code as a script, but still I like to use what the T.A.' S will be using.
Dec 25, 2017 - Sep 24, 2017. Warning: The P-code file system01.p was generated prior to MATLAB version 7.5 (R2007b) and will not be supported in a future. Hello, while doing some semestral works in MATLAB, I just ran into a.p file, which I had no idea of its existence until now (I knew only So, this is my question - does anybody know the way how to decrypt it into the.m file or another 'readable' form?
So to finally get to the point. When I type hw5pretest at the Octave prompt I get 'error: `hw5pretest' undefined near line 3 column 1' Does Octave support.p files? Thanks Manny Help-octave mailing list. Hi everyoneI am taking a 'Matlab for engineers' class and I have been using Octave instead so for with great results. Thanks for the good work.

Thanks Manny No,.p are precompiled.m files (compiled with a command called 'pcode' in Matlab) and Octave doesn't have such a compiler. Thomas Help-octave mailing list.

. — 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 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.
Myscript; 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 (MATLAB Compiler).
