2    
3            * src/dsCMatrix.c (dsCMatrix_LDL_D): cleanup, also using
4            internal_chm_factor().
5    
6            * R/AllGeneric.R: do *not* define a "chol" generic
7                    (but rather use the implicit one *without* making pivot
8                    part of the signature)
9            * R/*.R: drop the 'pivot' from chol's signature and make
10                    'pivot=FALSE' a default argument of method definitions.
11

166            order to match the generic (and evade .local(..)).

227    
228            * R/ngTMatrix.R: allow as(<numeric matrix>, "ngTMatrix") and hence
229            coercion to "nMatrix" and "pMatrix"
