LAPACK
LAPACK is a linear algebra library, based on LINPACK and EISPACK, designed to provide routines for handling simultaneous equations and matrix algebra efficiently, particularly on shared memory vector processors, parallel processors, and clusters. The code is written in Fortran, and requires the BLAS (Basic Linear Algebra Subprograms) library.

Release Notes: This release adds xGEQRT, a QR factorization facility that enables better performance when the blocked reflectors need to be reused. It adds xGEQRT3, a recursive QR factorization facility that has high performance on tall and skinny matrices. It adds xTPQRT, a collection of Communication-Avoiding QR sequential kernels. It replaces the build system with CMAKE for better portability. It adds Doxygen documentation. It integrates LAPACKE's C language APIs into LAPACK.

Re: The license is the modified BSD, not original BSD.
My bad, but I'm pleading insanity. I've updated the record,
in either case. :)
The license is the modified BSD, not original BSD.
See the COPYING file in the latest version. The
license
prior to 3.1 may have been fuzzy, but it has never been
the original BSD license. Using LAPACK has never
required an advertisement, although we'd really
appreciate a citation.
The license is now given explicitly in the COPYING
file,
and it is essentially the BSD
license without the advertising clause.
