BSctx_set_pre(3)                 BlockSolve95                 BSctx_set_pre(3)

NAME
       BSctx_set_pre - The preconditioner to be used by the iterative solver.

INPUT PARAMETERS
       context
              - The context to change
       pre    - The desired preconditioner
                The preconditioner choices are:
                  PRE_DIAG - diagonal preconditioning
                  PRE_ICC - incomplete Cholesky
                  PRE_ILU - incomplete LU
                  PRE_SSOR - SSOR
                  PRE_BJACOBI - block Jacobi

RETURNS
       void

NOTES
       Must agree with the preconitioner that has been computed!  If PRE_ICC
       is selected, BSset_mat_icc_storage() must be set to TRUE before
       BSmain_perm().  If PRE_ILU is selected, BSset_mat_icc_storage() must be
       set to FALSE.

SYNOPSIS
       void BSctx_set_pre(BSprocinfo *context, int pre)
