Is there a way to read the file?

Hi,

There might a copuple of different cases of this issue.

Easy solution can be to open that file with a notepad and then copy the code into MATLAB editor.

Good luck.

hi,

Thanks for the response.It didn't work, but let me help you. I have a matlab app in my pc that runs a couple of .m files. This app was created in 2014 and runs with MATLAB Compiler Runtime version 7.15. I want to read these files to convert in java code.

Thanks in advance

The .m files that are stored inside a application compiled with MATLAB Compiler, are AES encrypted. It is deliberate that you should not be able to read the files.

If you need the source code for an .m file that is compiled with MATLAB Compiler, you should go back to the source of the compiled application and ask for the source code (but do not be surprised if they decline to provide it.)

would u like to give me an email to send you the code? It is a must to open these files for my diploma thesis

[Walter Roberson]

I would not be able to open the files without breaking the encryption, which is something that I have no interest in doing.

Furthermore, the encrypted files are not in source code: they are encrypted versions of pcode files, so there would be an additional step of decoding the decrypted files.

My understanding is that these things are technically possible for a sufficiently determined person, but I am not sufficiently determined.

The legalities of the situation vary according to jurisdiction. In my country, in order to break the encryption without violating my Mathworks license, I might be required to prove that I am considered a "security researcher". Which is not something I could reasonably claim to be at present.

If you need the source code for a compiled MATLAB application, you should be talking to the people who published the application.
