Arguments

a type(psb_xspmat_type), intent(in).

The sparse matrix structure containing the local part of the matrix to be preconditioned. Note that x must be chosen according to the real/complex, single/double precision version of MLD2P4 under use. See the PSBLAS User's Guide for details [11].

desc_a type(psb_desc_type), intent(in).

The communication descriptor of a. See the PSBLAS User's Guide for details [11].

p type(mld_xprec_type), intent(inout).

The preconditioner data structure. Note that x must be chosen according to the real/complex, single/double precision version of MLD2P4 under use.

info integer, intent(out).

Error code. If no error, 0 is returned. See Section for details.
