|
|
! Subroutine: psb_zspins
|
|
! 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.
|
|
!
|
|
! Parameters:
|
|
! 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(:) - complex The values of the coefficients to be inserted.
|
|
! a - type(<psb_dspmat_type>). 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.
