Classes and methods for dense and sparse matrices and
operations on them using Lapack and SuiteSparse.
R (>= 2.9.0), stats, methods, utils, lattice
no longer available, since we use data/*.R *and* our
classes
The Matrix package includes libraries AMD, CHOLMOD,
COLAMD, CSparse and SPQR from the SuiteSparse collection of Tim
Davis.  All sections of that code are covered by the GPL or
LGPL licenses.  See the directory doc/UFsparse for details.
