Description

example

pcode(item) obfuscates the code in a .m file or folder on the search path and produces P-files with the extension .p. If item is a .m file, then the resulting file is item.p. If item is a folder, then all script or function files in that folder are obfuscated in the current folder. A P-file takes precedence over the corresponding .m file for execution, even after modifications to the .m file.

Note

The pcode function obfuscates your program files and does not encrypt them, thus P-files should not be considered secure. P-coding files to protect your intellectual property is not recommended.

There are some effective strategies for preventing people from copying your code for use in an exam:

• make your program so unpleasant to use that people would rather write their own code
• make your program give obviously wrong answers
• don't give anyone else access to the program
• Encrypt part of the program and prompt the user for a password that is used as a key to decrypt some of the m files, and do not tell anyone else what the key is. For better effect, if the wrong key is entered, instead of just failing, give wrong answers
