Description
            The goal of this toolbox is to provide iterative methods for sparse linear least
squares problems. This methods work with the iterative GMRES method for both
underdetermined and overdetermined problems and use various preconditionning
algorithms.

This module provides :

 * AB-GMRES and BA-GMRES without any particular preconditionner,
 * Robust Incomplete Factorization (RIF) preconditioning method working with
AB-GMRES and BA-GMRES,
 * Greville's preconditioning method working with AB-GMRES and BA-GMRES,
 * inner iterations preconditioning process with AB-GMRES and BA-GMRES.


Features
--------

 * splspc_gmresab : the AB-GMRES iterative solver
 * splspc_gmresba : the BA-GMRES iterative solver
 * splspc_rifgmresab : the AB-GMRES iterative solver with a RIF preconditioner
 * splspc_rifgmresab : the BA-GMRES iterative solver with a RIF preconditioner
 * splspc_grevgmresab: the AB-GMRES iterative solver with a GREVILLE
preconditioner
 * splspc_grevgmresba: the BA-GMRES iterative solver with a GREVILLE
preconditioner
 * splspc_nrsorgmresba: the BA-GMRES iterative solver with an inner iteration
preconditioner

The version v0.1 is correctly packaged on Windows. I checked this with Windows Vista and 
Scilab 5.3.2:

-->atomsSystemUpdate()
-->atomsInstall('splspc')
