Here's a page from the libc manual confirming this:

idx?  A vector of indices is an idx_vector, so a singleton must be
an idx.  Seems too short and likely to conflict with user variable 
names.

octave_idx? Seems good.  We index octave_values with octave_idx.

Index?  Also good.  We index ArrayN<T> values with Index.  Since Index
is fundamental to the Array class and the rest of the class doesn't use 
the
octave_ ``namespace'', this would be my choice.  It seems a bit generic
though.
