NAME

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

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)
