BLAS1_D is a C library which implements the Level 1 BLAS, or Basic Linear Algebra Subprograms.
The BLAS are a small core library of linear algebra utilities, which can be highly optimized for various architectures. Software that relies on the BLAS is thus highly portable, and will typically run very efficiently.
The Level 1 BLAS are primarily for use in vector operations. In certain cases, they may also be used to operate on the rows or columns of a two-dimensional array.

BLAS1_D is available in a C version and a C++ version and a FORTRAN77 version and a FORTRAN90 version and a MATLAB version and a Python version.
BLAS0, a C library which contains auxilliary functions for the Basic Linear Algebra Subprograms (BLAS).
BLAS1_C, a C library which contains basic linear algebra routines for vector-vector operations, using single precision complex arithmetic.
BLAS1_S, a C library which contains basic linear algebra routines for vector-vector operations, using single precision real arithmetic.
BLAS1_Z, a C library which contains basic linear algebra routines for vector-vector operations, using double precision complex arithmetic.
BLAS2, a C library which contains basic linear algebra subprograms (BLAS) for matrix-vector operations;
BLAS3, a C library which contains basic linear algebra subprograms (BLAS) for matrix-matrix operations;
CLAPACK, C programs which illustrate the use of the CLAPACK library, a translation of the FORTRAN77 BLAS and LAPACK linear algebra libraries, including single and double precision, real and complex arithmetic.
LINPACK, a C library which solves linear systems using double precision real arithmetic;
SUPER_BLAS, a C library which implements some of the Basic Linear Algebra Subprograms for fast execution.
SVD_DEMO, a C program which demonstrates the Singular Value Decomposition (SVD) for a simple example.
