LAPACK Description

Free linear algebra package for your Mac LAPACK is written in Fortran90 and provides routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems. The associated matrix factorizations (LU, Cholesky, QR, SVD, Schur, generalized Schur) are also provided, as are related computations such as reordering of the Schur factorizations and estimating condition numbers. Dense and banded matrices are handled, but not general sparse matrices. In all areas, similar functionality is provided for complex and real matrices, in both double and single precision. What's New in This Release: Improvements: · change xLARRD (MRRR routines) to deal with some matrices from Godunov · svn :: r630 · improvements provided by Christof Voemel on Tue Jan 27 2009 · commited by Julien Langou (SVN revision 630) on Wed Jan 28 2009 · see: svn log from Julien · change routines from xLARFG to xLARFP (they were missed in the first round) · svn :: r645 · routines :: SRC/cgeqpf.f, SRC/claqp2.f, SRC/claqps.f, SRC/clatrz.f, SRC/ctzrqf.f, and SRC/slaqp2.f Thanks to Michael Chuvelev from Intel for noting that the following routines still called xLARFG rather than xLARFP: · cgeqpf.f, slaqp2.f, claqp2.f, claqps.f, clatrz.f, and ctzrqf.f. · committed by Jason Riedy (SVN revision 645) on Fri Mar 6 2009 · Updated documentation for EPIR routines.
