MATLAB: How to prevent the P-code from being re-distributed

applicationcopycreationdatedeploydistributehideMATLABpcodepreventtimeuser

I want to protect my code and hide the algorithm when I distributed my application to my customer. I will use the PCODE function to protect my code but I would also like to prevent the user from distributing the application to someone else.

The ability to automatically protect P-code from being copied is not directly available in MATLAB.

There are no workarounds. You may hard-code some elements within the code that would fail some checks once the files are copied, but these methods are not fool-proof.

MATLAB: How to disable the compilation of a P-code file using the MATLAB Compiler 4.0 (R14)

In order to prevent P-code from running in stand-alone mode, you can implement one IF statement in the MATLAB code which is used to generate P-code. This method uses a call to the ISDEPLOYED function in order to determine if the code is running in a stand-alone application or within MATLAB.

Note that unlike prior versions of the MATLAB Compiler, C code is not generated, and proprietary information you wish to keep in the p-code file is maintained as proprietary. The prevention of compilation of P-code in the Compiler 4.0 does not apply as significantly as it did in prior versions of the Compiler. In prior versions, the main reason to prevent compilation of these files was to preserve intellectual property, but this is no longer necessary as it is still be encrypted as P-code format in a standalone application. The external pragma ("%#external") can be used to prevent a P-code file from being compiled:

function myPCodeFunction
%#external
desiredCode      % Run the main portion of code
end

Again, although technically the P-code can be compiled to a standalone application, in this case it is kept both proprietary and disabled for deployment. It works because the external pramga tells the MCC compiler to use an external implementation of any MATLAB or P-file it appears in. When someone tries to build an application with the file, they will receive an error when the program tries to link the files together.
