obfuscate or protect code / analogon to pcode of Matlab

[Bernhard Willert]

Hi,

I want to create a "black box" function, so that students can test their
algorithms on it without knowing its content.
Nearly any kind of obfuscation would do it as long as it is architecture
indepentent. In Matlab I have used pcode and a seperate m-file for help
texts but sadly octave cannot handle the resulting p-files.

Is there any analogon to pcode or a different trick to create a black
box? (I also have a C implementation of the function, maybe this can be
used.)

Best regards,
Bernhard
