I cleaned up the makefile -and created a second() function. This is used by linpack, eispack, and -lapack. -BLAS stands for Basic Linear Algebra (System?). It is a Fortran library, but -can be called from C, C++, or whatever. +The BLAS (Basic Linear Algebra Subprograms) are high quality "building +block" routines for performing basic vector and matrix operations. Level 1 +BLAS do vector-vector operations, Level 2 BLAS do matrix-vector operations, +and Level 3 BLAS do matrix-matrix operations. Because the BLAS are +efficient, portable, and widely available, they're commonly used in the +development of high quality linear algebra software, LINPACK and LAPACK for +example. + +A Fortran77 reference implementation of the BLAS is located in the blas +directory of Netlib. |
