No. The closest is boost.bindings which looks like it will languish in the
sandbox forever. How do you define matrix decompositions and inverses for
multidimensional arrays? If you are looking for multidimensional storage out
of which you can extract matrices and vectors for linear algebra, HDF5  is
a good choice. You may also want to look at F. Alted's Blosc  compression
library to use in conjunction with HDF5.
