Matrix (version 0.95-3)

dpoMatrix-class: Positive semi-definite, dense, numeric matrices

Description

The "dpoMatrix" class is the class of positive-semidefinite symmetric matrices in nonpacked storage. The "dppMatrix" class is the same except in packed storage. Only the upper triangle or the lower triangle is required to be available.

Objects from the Class

Objects can be created by calls of the form new("dpoMatrix", ...) or from crossprod applied to an "dgeMatrix" object.

Extends

Class "dsyMatrix", directly. Class "dgeMatrix", by class "dsyMatrix". Class "Matrix", by class "dsyMatrix".
