# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.  Line
# up the first '|' above the ':' following the base package name, and the '|'
# on the right side marks the last column you can put a character in.  You must
# make exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':'.

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