Virtual 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.

Class `"Matrix"`

, directly.

- 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.

The matrix factorization classes
`"'>MatrixFactorization"`

and their generators,
`lu()`

,
`qr()`

,
`chol()`

and `Cholesky()`

,
`BunchKaufman()`

, `Schur()`

.
