Class "syMatrix" of symmetric matrices

Description

The "syMatrix" class is the class of symmetric matrices in non-packed storage. Only the upper triangle or the lower triangle is stored.

Objects from the Class

Objects can be created by calls of the form new("syMatrix", ...).

Slots

uplo:

Object of class "character". Must be either "U", for upper triangular, and "L", for lower triangular.

x:

Object of class "numeric". The numeric values that constitute the matrix, stored in column-major order.

Dim:

Object of class "integer". The dimensions of the matrix which must be a two-element vector of non-negative integers.

norm:

Object of class "numeric". A named numeric vector of norms of the matrix. Some possible components are "O", the one norm; "I", the infinity norm; "F", the Frobenius norm; and "M", the maximum absolute value.

rcond:

Object of class "numeric". A named numeric vector of reciprocal condition numbers in either the 1-norm "O" or the infinity norm "I".

factorization:

Object of class "list". A named list of factorizations that have been computed for the matrix.

Extends

Class "geMatrix", directly. Class "Matrix", by class "geMatrix".
