I'm also interested in multidimensional iterators, and in general in
multidimensional data structures where the rank is not known until
run-time. Blitz++ and POOMA, AFAICS, require rank to be known at
compile-time since their data structures require tensor dimensions as
template parameters.
Does anyone know of any other good libraries that support both
multidimensional iterators and run-time rank?
It looks from the docs like AIPS++ supports these features pretty well.
But I'm not an astronomer. Is there a distribution of AIPS++ that just
has the basic data structures? If not, can they be used anyway without
building and learning about glish and the rest of the library? I've never
come across AIPS++ before... Is this because of its specialist niche, or
is there some other reason it doesn't seem to be used or discussed that
widely outside of the radio-astronomy community?
TIA,
Jeremy
