compMatrix-class Class "compMatrix" of Composite (Factorizable) Matrices

Description

Virtual class of composite matrices; i.e., matrices that can be factorized, typically as a product of simpler matrices.

Objects from the Class

A virtual Class: No objects may be created from it.

Slots

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.

Extends

Class "Matrix", directly.

Methods

dimnames<-

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.
