Hello dear experts of Matlab, i would like to ask that is it possible to decompile a previously made Matlab project(compiled as .exe) ? I compiled my .m and .fig files into a just one .exe file since i did not want the others see my codes inside, but i am not sure if there is a program which decompiles the included files in an exe file. If so, is there another way to hide the codes of your .m files? Can you please give information about this?

Hi,
MATLAB Compiler decrypts the m files binary style. There is no program available which decodes your m files so that you can read it again.
Theoretically it should be possible to encrypt it, but this is tough and pretty hard.

Friedrich, the thing you mean is that when i make an exe file, someone cannot read the .m file codes, right? If so, i will be really happy...
thnx..

Hi Kaan,
yes, noone can read the files anymore after compiling. So its a safe way to protect your code.

You can also hide your code as *.p files. It sounds like this approach might better suit you.
doc pcode

if you enter:
doc pcode
at the MATLAB command line, it will give you instructions on how to convert your mcode to pcode. This will mean you can give your friends the *.p file, they can run it just like any other file, but they can't see the code under the hood.

P-coding has a limited protection level only. You can e.g. still use the debugger the examine the contents of the functions.
