2    
3            * src/CHMfactor.c (CHMfactor_to_sparse): change LDL factorization
4            to LL before converting to a sparse matrix. (The LDL form can be
5            converted to a sparse matrix but it is implicitly a unit
6            triangular matrix and a diagonal matrix overwritten on the diagonal.)
