Welcome to the Scientific Library project

Introduction

The Scientific Library (named sl++) is a C++ object oriented library which tries to answer to a growing demand for a free, fast, easy to use and powerful numerical library. sl++ is composed of modules specialized in various fields of numerical computations. Each new module extends the possibilities of the library. The list of included modules and sub-modules is (future modules are in italic):

algebra provides advanced matrix operators and structures.
complex provides full arithmetic on complexes.
filter will provide various kind of adaptive filters.
fixed will provide fixed point arithmetic.
matrix provides basic matrix operators.

banded provides banded matrix structure.
colmajor provides dense column major matrix structure.
constant provides constant matrix structure.
diagonal provides diagonal matrix structure.
rowmajor provides dense row major matrix structure.
sss provides sparse symmetric skyline matrix structure.
symmetric provides dense symmetric matrix structure.
tensor3 provides 3D dense matrix structure.
triang provides dense lower and upper triangular matrix structures.
tvector provides dense vector matrix structure (vectors are a subset of matrices).

noise will provide various kind of noise generators.
plot will provide features for plotting matrices (requires gnuplot).
quaternion provides full arithmetic on quaternions.
spectral will provide discrete Fourier transform and related operators (requires fftw).

sl++ is a free software under the terms of the GNU General Public License.

Downloading

First beta release of the sl++ will be available when egcs will fully support template specialization. Until this date, we will only provide a copy of the development tree sl-0.0.6.tar.gz as well as a documentation package sl-0.0.6.doc.tar.gz.

Installation

Assuming you are on a Unix system, you can do:

#cd sl++
#./configure
#make
#make install

For the last command, you must have write access on the install directory. For more information about configuration you can do:

#./configure --help

or read the online installation instructions here.

Documentation

Online documentation can be found here.

The FAQ can be found here (not yet available).

Mailing lists

There are five mailing lists for sl++ located at pcmath03.insa-lyon.fr and managed by majordomo:

sl is a general list for developer discussions.
sl-announce is a read-only list where important events or releases are posted.
sl-bugs is for reporting and discussing bugs.
sl-cvs is for CVS check in messages.
sl-patches is for patch submissions.

To subscribe to any of these, send mail to sl-request, sl-announce-request, sl-bugs-request, sl-cvs-request, sl-patches-requestwith a message body of

subscribe listname your-email-address

To unsubscribe, send a mail note to the appropriate -request@mathinsa.insa-lyon.fr address with a message body of

unsubscribe listname your-email-address

Web archives for all these mailing lists are accessible on-line here.

CVS access

Read-only access to the sl++ development tree is provided via remote-CVS to anyone on the net. Assuming you have CVS installed on your machine you can check out the sources with the following sequence of commands:

#setenv CVSROOT ':pserver:anoncvs@pclhc590.cern.ch:/cvs'
#cvs login
>CVS password: anoncvs
#cvs -z 6 co sl++

Once you have got the repository checked out, you can use again the last previous command or the following commands:

#cd sl++
#cvs update

in order to synchronize your local copy with those in the repository.

Last stable pre-release of the sl++ library can be checked out with the command:

#cvs -z 6 co -r release-0-0-6 mta

Read-write access is only allowed to a restricted set of external developers. Ask to Laurent Deniauif you want to become an active developer and get a such access.

See the CVS manual for additional information on how to use CVS.

Development

For development, you will need basic tools like make, perl 5, m4 and of course a C++ compiler and your favourite editor.

For the repository access you will need:

CVS 1.9

For the configuration you will need:

Autoconf 2.12
Automake 1.3
Libtools 1.2

For the documentation you will need:

Doc++ 3.01
LaTeX 2e
