matrix objects representing several sparse storage formats currently in use
(in this release: compressed row, compressed column and coordinate formats),
providing basic functionality for managing sparse matrices, together with
efficient kernel mathematical operations (e.g. sparse matrix-vector multiply).

used in iterative solvers for linear systems of equations. The focus is on
computational support for iterative methods, but the sparse matrix objects
presented here can be used on their own.)

SparseLib++ v. 1.6: Numerical Sparse Matrix Classes in C++
SparseLib++ is a C++ class library for efficient sparse matrix computations
across various computational platforms. The software package consists of
matrix objects representing several sparse storage formats currently in use
(in this release: compressed row, compressed column and coordinate formats),
providing basic functionality for managing sparse matrices, together with
efficient kernel mathematical operations (e.g. sparse matrix-vector multiply).
Routines based on the Sparse BLAS are used to enhance portability and
performance. Included in the package are various preconditioners commonly
used in iterative solvers for linear systems of equations. The focus is on
computational support for iterative methods, but the sparse matrix objects
presented here can be used on their own.
Version 1.6 has been updated to adhere to the latest ANSI C++ standards,
including complex(> class, iostreams, and updated MV++ library.
1) More About SparseLib++
------------------------
i) User's Guide and man-style pages are available via
WWW: http://gams.cam.nist.gov/acmd/Staff/RPozo/sparselib++.html
ii) Code examples are in ./testing/*.cc
2) Installing SparseLib++ library
----------------------------------
You'll need to build the following three libraries
./lib/libmv.a MV++ basic matrix/vector library
./lib/libsparselib.a sparse matrix library
./lib/libspblas.a sparse BLAS library
i) cd to root directory where SparseLib++ will be installed
ii) edit makefile.def to specify your specify your particular C++ compiler
iii) type "make sp". ("make" by itself will provide a list of options.)
3) Testing SparseLib++
----------------------
i) cd to SparseLib++ root dir
ii) "make test" will run a test suites and leave their output in
./testing/sp_test.out.
4) Package components
---------------------
i) SparseLib++ and Sparse BLAS include files are in ./include
ii) SparseLib++ and Sparse BLAS libraries are in ./lib
iii) Lower-level Fortran-compatible Matrix/Vector library (MV++)is in
./lib/libmv.a
5) Help!
--------
Questions, comments, suggestions, etc. can be sent to pozo@cam.nist.gov.
6) #include
------------------------------
Be aware that SparseLib++ has been tested with GNU g++ 2.6.3, and 2.7.0
together with Sun C++ (CC) v. 4.0.1. and may not necessarily work with earlier
versions of these compilers. To find out the version of your compiler
use "g++ -v" or "CC -V foo".
