Lapack Libraries at SCS

Description

LAPACK, a Linear Algebra Package library, is written in Fortran77 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 real and complex matrices, in both single and double precision. See the LAPACK pages for additional information.

General Use

Lapack provides a library of routines that can be linked to your executables. Use a linker option -llapack to include the LAPACK library of routines. Note that you may need to also link to the blas library.

Cluster Specific Use

Phoenix

• The lapack libraries are already included as part of the OS distribution. Simply add -llapack to you linker statement to use the lapack libraries.
• These lapack versions have been compiled with gcc.
