Functionality

- -

uBLAS provides templated C++ classes for dense, unit and sparse vectors, -dense, identity, triangular, banded, symmetric, hermitian and sparse matrices. -Views into vectors and matrices can be constructed via ranges or slices and -adaptor classes. The library covers the usual basic linear algebra operations -on vectors and matrices: reductions like different norms, addition and subtraction -of vectors and matrices and multiplication with a scalar, inner and outer -products of vectors, matrix vector and matrix matrix products and triangular -solver. The glue between containers, views and expression templated operations -is a mostly STL - conforming iterator interface.
