lava (version 1.9.3)

Inverse: Generalized matrix inverse

Description

Generalized matrix inverse

Usage

Inverse(
  X,
  tol = lava.options()$itol,
  det = TRUE,
  names = !chol,
  chol = FALSE,
  symmetric = FALSE
)

Value

Matrix (generalized inverse of X). Attributes include det

(determinant), pseudo (logical, whether pseudo-inverse was used), and minSV (minimum singular value).

Arguments

X

nxn matrix

tol

tolerance for pseudo inverse

det

logical, if true the determinant is returned

names

preserve dimnames

chol

use Cholesky decomposition for calculating inverse otherwise SVD

symmetric

set to true if matrix is symmetric
