BLAS2_S
Single Precision Real MatrixVector Basic Linear Algebra Subprograms
BLAS2_S
a C++ library which
constitutes the Level 2 Basic Linear Algebra Subprograms (BLAS),
for matrixvector operations,
using single precision real arithmetic.
The BLAS are a small core library of linear algebra utilities,
which can be highly optimized for various architectures.
