The SFLC has advised us to make sure we do not read Matlab code when implementing Octave code. The only thing that is known to legally work is clean-room reverse engineering. It's ok to read independently-written specifications of how the software works and reimplement that. Reading the software itself and reimplementing it constitutes a strong case for derivative work.
