It's been a while but I seem to recall LEDA can deal with
multidimensional matrices. I also have some stuff that deals with
multidimensional arrays. As far as my own stuff goes, I am not
satisfied with it and have every intention of scrapping or rewriting it,
but it does come with interfaces to HDF5... I too would like to know of
any decent multi-dim array or matrix stuff available.

For myself, I am currently dealing with a lot of 2 and 3-D data sets and
their manipulation. At the moment I am using all the basic types and
will need to start using Rationals soon. Also, some of my data sets are
huge and need to be sub sampled efficiently (one 2-D data set is 3 GB,
and I've read of another researcher who is trying to cope with one that
is roughly a TeraByte).

As for algorithms: computing the Vornoi diagram and intersections of
polytopes is what I could use most now.
