compMatrix-class
Class "compMatrix" of Composite (Factorizable) MatricesVirtual class of composite matrices; i.e., matrices that can be factorized, typically as a product of simpler matrices.
A virtual Class: No objects may be created from it.
factors
:Object of class "list"
- a list of factorizations of the matrix. Note that this is typically empty, i.e., list()
, initially and is updated automagically whenever a matrix factorization is computed.
Dim
, Dimnames
:inherited from the Matrix
class, see there.
Class "Matrix"
, directly.
signature(x = "compMatrix", value = "list")
: set the dimnames
to a list
of length 2, see dimnames<-
. The factors
slot is currently reset to empty, as the factorization dimnames
would have to be adapted, too.
