blas1_d, a Fortran77 code which constitutes the Level 1 Basic Linear Algebra Subprograms (BLAS), for vector-vector operations using double precision real arithmetic, by Charles Lawson, Richard Hanson, David Kincaid, Fred Krogh.
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.

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.
BLAS, a Fortran77 library which contains the Basic Linear Algebra Subprograms (BLAS) for level 1 (vector-vector operations), level 2 (matrix-vector operations) and level 3 (matrix-matrix operations), for single precision real arithmetic, double precision real arithmetic, single precision complex arithmetic, and double precision complex arithmetic.
BLAS0, a Fortran77 library which contains auxilliary functions for the Basic Linear Algebra Subprograms (BLAS).
LAPACK_EXAMPLES, a Fortran77 program which demonstrates the use of the LAPACK linear algebra library.
LINPACK, a Fortran77 library which is a linear algebra package which uses the BLAS1 routines.
SUPER_BLAS, a Fortran77 library which is a version of some of the BLAS1 routines written in C.
Original Fortran77 version by Charles Lawson, Richard Hanson, David Kincaid, Fred Krogh.
