gchol.bdsmatrix-class: Class "gchol.bdsmatrix"

In bdsmatrix: Routines for Block Diagonal Symmetric Matrices

Class "gchol.bdsmatrix"

Description

Generalized cholesky decomposition of a bdsmatrix object, A= LDL' where A is symmetric, L is lower triangular with 1 on the diagonal, and D is diagonal.

Objects from the Class

These are created by the gchol function.

Slots

blocksize:

Integer vector of block sizes

blocks:

Numeric vector containing the blocks

rmat:

Dense portion of the decomposition

rank:

The rank of A

Dim:

Integer vector of length 2 containing the dimension

Dimnames:

List of length 2 containing the dimnames

Note

The Cholesky decompostion of a block diagonal symmetric matrix is also block diagonal symmetric, so is stored in the same manner as a bdsmatrix object
