View source for BLAS LAPACK ScaLAPACK

A de facto standard API for linear algebra [http://en.wikipedia.org/wiki/Basic_Linear_Algebra_Subprograms BLAS]/[http://en.wikipedia.org/wiki/LAPACK LAPACK]
* Original http://www.netlib.org/blas/ http://www.netlib.org/lapack/ - implemented in Fortran. The libraries can be used in C/C++ (so called Fortran interface to BLAS/LAPACK).
* ATLAS http://math-atlas.sourceforge.net/ - provides a C interface to BLAS and partially LAPACK. Binary packages: libatlas-[base or platform name, for example sse2]
* MKL http://software.intel.com/en-us/intel-mkl/ - Intel implementation
*ACML http://developer.amd.com/libraries/acml/pages/default.aspx
*CUBLAS http://developer.nvidia.com/cublas

Using the C interface is preferable. [http://www.inf.bv.tum.de/~heisserer/softwarelab04/doc/blas_report.pdf BLAS: overview, installation, usage]
