I've implemented the Helical and Helical Scan interleavers. octave-forge/main/comm/inst. I'm not a member of the octave forge project, so I've just attached them. Enjoy. Alternately, someone could grant me commit access. My sourceforge user is https://sourceforge.net/users/mborg -- Mark

[OctDev] Access struct fields inside cell
