Preconditioner data structure
</H2>
Our base library offers support for simple well known preconditioners
like Diagonal Scaling or Block Jacobi with incomplete
factorization ILU(0).

A preconditioner is held in the precdata<TT> psb_prec_type</TT> data structure reported in
figure&nbsp;<A HREF="#fig:prectype">6</A>. The <code>psb_prec_type</code>
data type may contain a simple preconditioning matrix with the
associated communication descriptor.The internal preconditioner is allocated appropriately with the
dynamic type corresponding to the desired preconditioner.
