.— Convert some or all of your source code files to a content-obscuredform called a P-code file (from its.pfile extension), and distribute your application code in this format. WhenMATLAB P-codes a file, the file is obfuscated notencrypted. While the content in a.pfile is difficult to understand, it should not be considered secure. It is notrecommended that you P-code files to protect your intellectual property.MATLAB does not support converting live scripts or live functions toP-code files.— Compile your source code files using the MATLAB Compiler to produce a standalone application. Distribute thelatter to end users of your application.Building a Content Obscured Format with P-CodeA P-code file behaves the same as the MATLAB source from which it was produced. The P-code file also runs at thesame speed as the source file.

P-code files are purposely obfuscated. They are notencrypted. While the content in a.p file is difficult tounderstand, it should not be considered secure. It is not recommended that youP-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 changethe source code at some point after generating the P-code file. Remember toremove the.m source file before distributing yourcode.

Running Older P-Code Files on Later Versions of MATLABP-code files are designed to be independent of the release under which theywere created and the release in which they are used (backward and forwardcompatibility). New and deprecated MATLAB features can be a problem, but it is the same problem that wouldexist if you used the original MATLAB input file. To fix errors of this kind in a P-code file, fix thecorresponding 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 builtwith 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 builtwith MATLAB 7.4 or earlier using a more recent version of MATLAB, and then redistribute them as necessary. Building a Standalone ExecutableAnother way to protect your source code is to build it into a standaloneexecutable and distribute the executable, along with any other necessary files, toexternal customers. You must have the MATLABCompiler™ and a supported C or C compiler installed to prepare files fordeployment.

The end user, however, does not need MATLAB.To build a standalone application for your MATLAB application, develop and debug your application following the usualprocedure for MATLAB program files. Then, generate the executable file or files followingthe instructions in (MATLAB Compiler).

What access do you want the 'other user' to have to your data? As I understand it, you basically want to encrypt your file such that someone else cannot open and read your data. I'm not sure how you'll be able to do that in a.mat file- if you use Matlab to save the data in MAT format, the file will be written in such a way that it can be opened with Matlab, as that is the purpose of the file format. I don't believe that Matlab has an equivalent of Excel's 'Protect Workbook' or similar. You can encrypt m-files such that they can be executed without revealing the source code (using the 'pcode' function), but that is obviously something different than you want.
