The Colin de Verdi`ere parameters mu and nu are defined to be the maximum nullity of
certain real symmetric matrices associated with a given graph. In this work, both of these parameters
are calculated for all chordal graphs. For nu the calculation is based solely on maximal cliques, while
for μ the calculation depends on split subgraphs. For the case of μ our work extends some recent
work on computing μ for split graphs.
