!
! Subroutine: psb_dspins
! Takes a cloud of coefficients and inserts them into a sparse matrix.
! Note: coefficients with a row index not belonging to the current process are
! ignored.
! If desc_a is in the build state this routine implies a call to psb_cdins.
!
! Arguments:
! nz - integer. The number of points to insert.
! ia(:) - integer The row indices of the coefficients.
! ja(:) - integer The column indices of the coefficients.
! val(:) - real The values of the coefficients to be inserted.
! a - type(psb_d_sparse_mat). The sparse destination matrix.
! desc_a - type(psb_desc_type). The communication descriptor.
! info - integer. Error code
! rebuild - logical Allows to reopen a matrix under
! certain circumstances.
!
