The virtual class "CHMfactor" is a class of
CHOLMOD-based Cholesky factorizations of symmetric, sparse,
compressed, column-oriented matrices. Such a factorization is
simplicial (virtual class "CHMsimpl") or supernodal (virtual
class "CHMsuper"). Objects that inherit from these classes are
either numeric factorizations (classes "dCHMsimpl" and
"dCHMsuper") or symbolic factorizations (classes
"nCHMsimpl" and "nCHMsuper").
Arguments
Objects from the Class
Objects can be created by calls of the form new("dCHMsuper", ...)
but are more commonly created via Cholesky().
applied to dsCMatrix or
lsCMatrix objects.
