Title: Sparse and Dense Matrix Classes and Methods
Author: Douglas Bates <bates@stat.wisc.edu> and Martin
Maechler <maechler@stat.math.ethz.ch>
Maintainer: Doug and Martin <Matrix-authors@R-project.org>
Description: Classes and methods for dense and sparse matrices
and operations on them using Lapack and
SuiteSparse.
Depends: R (>= 2.9.0), stats, methods, utils, lattice
Imports: graphics, lattice, grid, stats
Enhances: graph, SparseM
SystemRequirements: GNU make
LazyLoad: yes
LazyData: no
LazyDataNote: no longer available, since we use data/*.R *and*
our classes
License: GPL (>= 2)
LicenseDetails: 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.
