SUMMARY="A C++ linear algebra library"
DESCRIPTION="The library provides efficient classes for vectors, matrices and \
cubes, as well as 200+ associated functions (eg. contiguous and non-contiguous \
submatrix views). Various matrix decompositions are provided through \
integration with LAPACK, or one of its high performance drop-in replacements."
