Well ... yes and no ;o)

ublas is BLAS (i.e. Basic Linear Algebra Subroutines) written in C++,
so it provides (only) elementary vector and matrix operation (scaling,
addition, matrix/vector and matrix/matrix multiplication etc.).

But we are developing `bindings' library which provides interfaces
to some Fortran and C numeric libraries, e.g. ATLAS and LAPACK,
so that they can be used with ublas matrices and vectors.

Current version of `bindings' library (not complete, but IMHO
useable) can be found in the boost sandbox

with documentation and examples in

You can also download complete zip archive from the files section
of the ublas-dev mailing list

(I think that you must join the mailing list to access the files:

    ublas-dev-subscribe_at_[hidden] .)
