! Subroutine: mld_c_dec_aggregator_mat_asb
! Version: complex
!
! This routine builds the matrix associated to the current level of the
! multilevel preconditioner from the matrix associated to the previous level,
! by using the user-specified aggregation technique (therefore, it also builds the
! prolongation and restriction operators mapping the current level to the
! previous one and vice versa).
! The current level is regarded as the coarse one, while the previous as
! the fine one. This is in agreement with the fact that the routine is called,
! by mld_mlprec_bld, only on levels >=2.
! The coarse-level matrix A_C is built from a fine-level matrix A
! by using the Galerkin approach, i.e.
!
! A_C = P_C^T A P_C,
!
! where P_C is a prolongator from the coarse level to the fine one.
!
! A mapping from the nodes of the adjacency graph of A to the nodes of the
! adjacency graph of A_C has been computed by the mld_aggrmap_bld subroutine.
! The prolongator P_C is built here from this mapping, according to the
! value of p%iprcparm(mld_aggr_kind_), specified by the user through
! mld_cprecinit and mld_zprecset.
! On output from this routine the entries of AC, op_prol, op_restr
! are still in "global numbering" mode; this is fixed in the calling routine
! mld_c_lev_aggrmat_asb.
!
! Currently four different prolongators are implemented, corresponding to
! four aggregation algorithms:
! 1. un-smoothed aggregation,
! 2. smoothed aggregation,
! 3. "bizarre" aggregation.
! 4. minimum energy
! 1. The non-smoothed aggregation uses as prolongator the piecewise constant
! interpolation operator corresponding to the fine-to-coarse level mapping built
! by p%aggr%bld_tprol. This is called tentative prolongator.
! 2. The smoothed aggregation uses as prolongator the operator obtained by applying
! a damped Jacobi smoother to the tentative prolongator.
! 3. The "bizarre" aggregation uses a prolongator proposed by the authors of MLD2P4.
! This prolongator still requires a deep analysis and testing and its use is
! not recommended.
! 4. Minimum energy aggregation

! Subroutine: mld_s_dec_aggregator_mat_asb
! Version: real
!
! This routine builds the matrix associated to the current level of the
! multilevel preconditioner from the matrix associated to the previous level,
! by using the user-specified aggregation technique (therefore, it also builds the
! prolongation and restriction operators mapping the current level to the
! previous one and vice versa).
! The current level is regarded as the coarse one, while the previous as
! the fine one. This is in agreement with the fact that the routine is called,
! by mld_mlprec_bld, only on levels >=2.
! The coarse-level matrix A_C is built from a fine-level matrix A
! by using the Galerkin approach, i.e.
!
! A_C = P_C^T A P_C,
!
! where P_C is a prolongator from the coarse level to the fine one.
!
! A mapping from the nodes of the adjacency graph of A to the nodes of the
! adjacency graph of A_C has been computed by the mld_aggrmap_bld subroutine.
! The prolongator P_C is built here from this mapping, according to the
! value of p%iprcparm(mld_aggr_kind_), specified by the user through
! mld_sprecinit and mld_zprecset.
! On output from this routine the entries of AC, op_prol, op_restr
! are still in "global numbering" mode; this is fixed in the calling routine
! mld_s_lev_aggrmat_asb.
!
! Currently four different prolongators are implemented, corresponding to
! four aggregation algorithms:
! 1. un-smoothed aggregation,
! 2. smoothed aggregation,
! 3. "bizarre" aggregation.
! 4. minimum energy
! 1. The non-smoothed aggregation uses as prolongator the piecewise constant
! interpolation operator corresponding to the fine-to-coarse level mapping built
! by p%aggr%bld_tprol. This is called tentative prolongator.
! 2. The smoothed aggregation uses as prolongator the operator obtained by applying
! a damped Jacobi smoother to the tentative prolongator.
! 3. The "bizarre" aggregation uses a prolongator proposed by the authors of MLD2P4.
! This prolongator still requires a deep analysis and testing and its use is
! not recommended.

! Subroutine: mld_s_dec_aggregator_mat_bld
! Version: real
!
! This routine builds the matrix associated to the current level of the
! multilevel preconditioner from the matrix associated to the previous level,
! by using the user-specified aggregation technique (therefore, it also builds the
! prolongation and restriction operators mapping the current level to the
! previous one and vice versa).
! The current level is regarded as the coarse one, while the previous as
! the fine one. This is in agreement with the fact that the routine is called,
! by mld_mlprec_bld, only on levels >=2.
! The coarse-level matrix A_C is built from a fine-level matrix A
! by using the Galerkin approach, i.e.
!
! A_C = P_C^T A P_C,
!
! where P_C is a prolongator from the coarse level to the fine one.
!
! A mapping from the nodes of the adjacency graph of A to the nodes of the
! adjacency graph of A_C has been computed by the mld_aggrmap_bld subroutine.
! The prolongator P_C is built here from this mapping, according to the
! value of p%iprcparm(mld_aggr_kind_), specified by the user through
! mld_sprecinit and mld_zprecset.
! On output from this routine the entries of AC, op_prol, op_restr
! are still in "global numbering" mode; this is fixed in the calling routine
! mld_s_lev_aggrmat_bld.
!
! Currently four different prolongators are implemented, corresponding to
! four aggregation algorithms:
! 1. un-smoothed aggregation,
! 2. smoothed aggregation,
! 3. "bizarre" aggregation.
! 4. minimum energy
! 1. The non-smoothed aggregation uses as prolongator the piecewise constant
! interpolation operator corresponding to the fine-to-coarse level mapping built
! by p%aggr%bld_tprol. This is called tentative prolongator.
! 2. The smoothed aggregation uses as prolongator the operator obtained by applying
! a damped Jacobi smoother to the tentative prolongator.
! 3. The "bizarre" aggregation uses a prolongator proposed by the authors of MLD2P4.
! This prolongator still requires a deep analysis and testing and its use is
! not recommended.
! 4. Minimum energy aggregation

! File: mld_z_dec_aggregator_mat_bld.f90

! Subroutine: mld_z_dec_aggregator_mat_bld
! Version: complex
!
! This routine builds the matrix associated to the current level of the
! multilevel preconditioner from the matrix associated to the previous level,
! by using the user-specified aggregation technique (therefore, it also builds the
! prolongation and restriction operators mapping the current level to the
! previous one and vice versa).
! The current level is regarded as the coarse one, while the previous as
! the fine one. This is in agreement with the fact that the routine is called,
! by mld_mlprec_bld, only on levels >=2.
! The coarse-level matrix A_C is built from a fine-level matrix A
! by using the Galerkin approach, i.e.
!
! A_C = P_C^T A P_C,
!
! where P_C is a prolongator from the coarse level to the fine one.
!
! A mapping from the nodes of the adjacency graph of A to the nodes of the
! adjacency graph of A_C has been computed by the mld_aggrmap_bld subroutine.
! The prolongator P_C is built here from this mapping, according to the
! value of p%iprcparm(mld_aggr_kind_), specified by the user through
! mld_zprecinit and mld_zprecset.
! On output from this routine the entries of AC, op_prol, op_restr
! are still in "global numbering" mode; this is fixed in the calling routine
! mld_z_lev_aggrmat_bld.
!
! Currently four different prolongators are implemented, corresponding to
! four aggregation algorithms:
! 1. un-smoothed aggregation,
! 2. smoothed aggregation,
! 3. "bizarre" aggregation.
! 4. minimum energy
! 1. The non-smoothed aggregation uses as prolongator the piecewise constant
! interpolation operator corresponding to the fine-to-coarse level mapping built
! by p%aggr%bld_tprol. This is called tentative prolongator.
! 2. The smoothed aggregation uses as prolongator the operator obtained by applying
! a damped Jacobi smoother to the tentative prolongator.
! 3. The "bizarre" aggregation uses a prolongator proposed by the authors of MLD2P4.
! This prolongator still requires a deep analysis and testing and its use is
! not recommended.
! 4. Minimum energy aggregation
!

! The sparse matrix structure containing the local part of
! the fine-level matrix.
! desc_a - type(psb_desc_type), input.
! The communication descriptor of the fine-level matrix.
! The 'one-level' data structure that will contain the local
! part of the matrix to be built as well as the information
! concerning the prolongator and its transpose.
! ilaggr - integer, dimension(:), input
! The mapping between the row indices of the coarse-level
! matrix and the row indices of the fine-level matrix.
! ilaggr(i)=j means that node i in the adjacency graph

! are assumed to be shifted so as to make sure the ranges on
! the various processes do not overlap.
! nlaggr - integer, dimension(:) input
! nlaggr(i) contains the aggregates held by process i.
! ac - type(psb_zspmat_type), output
! The coarse matrix on output
!
! op_prol - type(psb_zspmat_type), input/output
! The tentative prolongator on input, the computed prolongator on output
!
! op_restr - type(psb_zspmat_type), output
! The restrictor operator; normally, it is the transpose of the prolongator.
