|

|

! Data structure(s) for sparse matrices
|

|
!
|
||
|
|
! This module defines:
|
||
|
|
! - the mld_prec_type data structure containing the preconditioner;
|
||
|
|
! - character constants describing the preconditioner, used by the routine
|
||
|
|
! printing out a preconditioner description;
|
||
|
|
! - the interfaces to the routines for the management of the preconditioner
|
||
|
|
! data structure (see below).
|
||
|
|
!
|
||
|
|
! It contains:
|
||
|
|
! - mld_dprec_sizeof, mld_dbaseprc_sizeof, mld_out_prec_descr, mld_file_prec_descr,
|
||
|
|
! mld_icheck_def, mld_dcheck_def, mld_dbase_precfree, mld_nullify_dbaseprec,
|
||
|
|
! is_legal_..._..., and their complex versions (if applicable).
|
||
|
|
! These routines check if the preconditioner is correctly defined, print a
|
||
|
|
! description of the preconditioner, and deallocate its data structure.
