3            * R/Tsparse.R ([): fix long standing typo in symmetric case
4            * man/dsCMatrix-class.Rd: add example exhibiting the above case
5

7    
8            * src/CHMfactor.c (CHMfactor_to_sparse): change LDL factorization

10            converted to a sparse matrix but it is implicitly a unit
11            triangular matrix and a diagonal matrix overwritten on the diagonal.)
