la.norms.slogdet

Compute the sign and natural logarithm of the absolute value of the determinant.

Syntax

la.norms.slogdet(A, options?)

Description

Compute the sign and natural logarithm of the absolute value of the determinant. Returns (sign, logabsdet) such that det(A) = sign * exp(logabsdet). This is the most numerically stable way to work with determinants, especially for large matrices or matrices with very large/small determinants.

Parameters

NameDescription
A- Input square matrix (n × n)
