inchol-class {kernlab} | R Documentation

## 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
