BLAS2_D
Double Precision Real Basic Linear Algebra Subprograms  Level 2
BLAS2_D,
a MATLAB library which
constitutes the Level 2 Basic Linear Algebra Subprograms (BLAS),
for matrixvector operations,
using double precision real arithmetic.
The BLAS are a small core library of linear algebra utilities,
which can be highly optimized for various architectures.
