Virtual Class "unpackedMatrix" of Unpacked Dense Matrices

Class "unpackedMatrix" is the virtual class of dense matrices in "unpacked" format, storing all m*n elements of an m-by-n matrix. It is used to define common methods for efficient subsetting, transposing, etc. of its proper subclasses: currently "[dln]geMatrix" (unpacked general), "[dln]syMatrix" (unpacked symmetric), "[dln]trMatrix" (unpacked triangular), and subclasses of these, such as "dpoMatrix".

Slots

Dim, Dimnames:

as all Matrix objects.

Extends

Class "denseMatrix", directly. Class "Matrix", by class "denseMatrix", distance 2.

Methods

pack

signature(x = "unpackedMatrix"): ...

unpack

signature(x = "unpackedMatrix"): ...

isSymmetric

signature(object = "unpackedMatrix"): ...

isTriangular

signature(object = "unpackedMatrix"): ...

isDiagonal

signature(object = "unpackedMatrix"): ...

t

signature(x = "unpackedMatrix"): ...

diag

signature(x = "unpackedMatrix"): ...

diag<-

signature(x = "unpackedMatrix"): ...
