lapack-atlas: lapack-atlas (LAPACK sources for build against ATLAS) lapack-atlas: lapack-atlas: LAPACK provides routines for solving systems of simultaneous linear lapack-atlas: equations, least-squares solutions of linear systems of equations, lapack-atlas: eigenvalue problems, and singular value problems. The associated lapack-atlas: matrix factorizations (LU, Cholesky, QR, SVD, Schur, generalized lapack-atlas: Schur) are also provided, as are related computations such as lapack-atlas: reordering of the Schur factorizations and estimating condition lapack-atlas: numbers. Dense and banded matrices are handled, but not general sparse lapack-atlas: matrices. In all areas, similar functionality is provided for real and lapack-atlas: complex matrices, in both single and double precision.
