For the ARMS preconditioner, one can use either the symmetric ARMS or the non-symmetric
variant (ARMS-ddPQ) by setting the permutation type with <A HREF="../PC/PCPARMSSetNonsymPerm.html#PCPARMSSetNonsymPerm">PCPARMSSetNonsymPerm</A>().
<P>
See the pARMS function parms_PCILUSetType for more information.
