BSset_diag(3)                    BlockSolve95                    BSset_diag(3)

NAME
       BSset_diag - Set the diagonal of A to a constant

INPUT PARAMETERS
       A      - a sparse matrix
       my_alpha
              - the constant
       procinfo
              - the usual processor stuff

OUTPUT PARAMETERS
       A      - a sparse matrix with the diagonal set to my_alpha

RETURNS
       void

       Notes:  In the nonsymmetric case we set the diagonal +/-my_alpha
       depending on the sign of the diagonal.

SYNOPSIS
       /* Set the diagonal of the matrix to my_alpha */
       void BSset_diag(BSpar_mat *A, FLOAT my_alpha, BSprocinfo *procinfo)
