| MatrixFactorization-class {Matrix} | R Documentation |
The class "MatrixFactorization" is the virtual (super) class of
(potentially) all matrix factorizations of matrices from package
Matrix.
A virtual Class: No objects may be created from it.
Dim:"integer" - the dimensions
of the original matrix - must be an integer vector with exactly two
non-negative values.(x) simply returns x@Dim, see above.signature(x = "MatrixFactorization"): this has
not been implemented yet for all matrix factorizations. It should
return a list whose components are matrices which when multiplied
return the original Matrix object.signature(object = "MatrixFactorization"): simple
printing, see show.signature(a = "MatrixFactorization", b= .):
solve A x = b for x; has not been implemented for
all factorizations, but e.g., for CHMfactor,
see there.
classes inheriting from "MatrixFactorization", such as
CHMfactor,
LU, and
sparseQR.
