<A NAME="sec:psprecs"></A>The base PSBLAS library contains the implementation of two simple
|
|
preconditioning techniques:
|
|
|
|
<UL>
|
|
<LI>Diagonal Scaling
|
|
</LI>
|
|
<LI>Block Jacobi with ILU(0) factorization
|
|
</LI>
|
|
</UL>
|
|
The supporting data type and subroutine interfaces are defined in the
|
|
module <code>psb_prec_mod</code>.
|
|
The old interfaces <code>psb_precinit</code> and <code>psb_precbld</code> are still supported for
|
|
backward compatibility
