inchol-class

Class "inchol"

Description

The reduced Cholesky decomposition object

Objects from the Class

Objects can be created by calls of the form new("inchol", ...). or by calling the inchol function.

Slots

.Data:

Object of class "matrix" contains the decomposed matrix

pivots:

Object of class "vector" contains the pivots performed

diagresidues:

Object of class "vector" contains the diagonial residues

maxresiduals:

Object of class "vector" contains the maximum residues

Extends

Class "matrix", directly.

Methods

diagresidues

signature(object = "inchol"): returns the diagonial residues

maxresiduals

signature(object = "inchol"): returns the maximum residues

pivots

signature(object = "inchol"): returns the pivots performed
