|
|
! Assemble sparse matrix
|
|
!
|
|
! Arguments:
|
|
! a - type(psb_d_sparse_mat). The sparse matrix to be allocated.
|
|
! desc_a - type(psb_desc_type). The communication descriptor.
|
|
! info - integer. return code.
|
|
! afmt - character(optional) The desired output storage format.
|
|
! upd - character(optional). How will the matrix be updated?
|
|
! psb_upd_srch_ Simple strategy
|
|
! psb_upd_perm_ Permutation(more memory)
|
|
! dupl - integer(optional). Duplicate coefficient handling:
|
|
! psb_dupl_ovwrt_ overwrite
|
|
! psb_dupl_add_ add
|
|
! psb_dupl_err_ raise an error.
