|
|
! Subroutine: psb_cdins
|
|
! Takes as input a cloud of points and updates the descriptor accordingly.
|
|
! Note: entries with a row index not belonging to the current process are
|
|
! ignored (see usage of ila_ as mask in the call to psb_idx_ins_cnv).
|
|
!
|
|
! Arguments:
|
|
! nz - integer. The number of points to insert.
|
|
! ia(:) - integer The row indices of the points.
|
|
! ja(:) - integer The column indices of the points.
|
|
! desc_a - type(psb_desc_type). The communication descriptor to be freed.
|
|
! info - integer. Return code.
|
|
! ila(:) - integer, optional The row indices in local numbering
|
|
! jla(:) - integer, optional The col indices in local numbering
