The whole copyright stuff is a pain! IANAL, but as far as I understand it: - it's ok to copy examples which have some open source licence, probably needing to keep that licence. - it's ok to re-do someone elses examples as long as you don't look at source code. However, that is probably a bit tricky as examples are usually mixed with code. - if unsure, ask the original author. This should work fine for academics and the like but probably less well for Mathworks.
This could be a PDE example to look into: http://wiki.scipy.org/PerformancePython Tutorials/examples would definitely be useful!
