! Subroutine: psb_sinsvi
|
|
! Insert dense submatrix to dense matrix. Note: the row indices in IRW
|
|
! are assumed to be in global numbering and are converted on the fly.
|
|
! Row indices not belonging to the current process are silently discarded.
|
|
!
|
|
! Arguments:
|
|
! m - integer. Number of rows of submatrix belonging to
|
|
! val to be inserted.
|
|
! irw(:) - integer Row indices of rows of val (global numbering)
|
|
! val(:) - real The source dense submatrix.
|
|
! x(:) - real The destination dense matrix.
|
|
! desc_a - type(psb_desc_type). The communication descriptor.
|
|
! info - integer. return code
|
|
! dupl - integer What to do with duplicates:
|
|
! psb_dupl_ovwrt_ overwrite
|
|
! psb_dupl_add_ add

! Subroutine: psb_sinsi
|
|
! Insert dense submatrix to dense matrix. Note: the row indices in IRW
|
|
! are assumed to be in global numbering and are converted on the fly.
|
|
! Row indices not belonging to the current process are silently discarded.
|
|
!
|
|
! Arguments:
|
|
! m - integer. Number of rows of submatrix belonging to
|
|
! val to be inserted.
|
|
! irw(:) - integer Row indices of rows of val (global numbering)
|
|
! val(:,:) - real The source dense submatrix.
|
|
! x(:,:) - real The destination dense matrix.
|
|
! desc_a - type(psb_desc_type). The communication descriptor.
|
|
! info - integer. return code
|
|
! dupl - integer What to do with duplicates:
|
|
! psb_dupl_ovwrt_ overwrite
|
|
! psb_dupl_add_ add
