chol_control {mcmcsae}

Set options for Cholesky decomposition

Description

These options are only effective in case the matrix to be decomposed is sparse, i.p. of class dsCMatrix-class.

Usage

chol_control(perm = NULL, super = NA, ordering = 0L, inplace = TRUE)

Arguments

perm

logical scalar, see Cholesky. If NULL, the default, the choice is left to a simple heuristic.

super

logical scalar, see Cholesky.

ordering

an integer scalar passed to CHOLMOD routines determining which reordering schemes are tried to limit sparse Cholesky fill-in.

inplace

whether sparse Cholesky updates should re-use the same memory location.

Value

A list with specified options used for Cholesky decomposition.
