Eigen_logabsdet {EigenR}

Logarithm of the absolute value of the determinant

Description

Logarithm of the absolute value of the determinant of a real matrix.

Usage

Eigen_logabsdet(M)

Arguments

M

a real square matrix

Value

The logarithm of the absolute value of the determinant of M.

Note

'Eigen_logabsdet(M)' is not faster than 'log(abs(Eigen_det(M)))'.

Examples

set.seed(666L)
M <- matrix(rpois(25L, 1), 5L, 5L)
Eigen_logabsdet(M)
