The process seems to go: cast scalars to 1-D arrays (hence #1 and #3), and indexing results in #2. The oddity is that the second and third arguments are optional, and the action of the function depends on that. I would have made those arguments required as omitting them gives the same as a call to nonzero. But things are as they are... Chuck
