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)
