det: Matrix Determinant

In madness: Automatic Differentiation of Multivariate Operations

Matrix Determinant

Description

Compute the determinant of a matrix. As for base::determinant, a list of the modulus and sign are returned.

Usage

## S3 method for class 'madness'
determinant(x, logarithm = TRUE, ...)

det(x, ...)

## S4 method for signature 'madness,ANY'
determinant(x, logarithm = TRUE, ...)

## S4 method for signature 'madness,missing'
determinant(x, logarithm = TRUE, ...)

## S4 method for signature 'madness,logical'
determinant(x, logarithm = TRUE, ...)

Arguments

x	madness object.
logarithm	logical; if TRUE (default) return the logarithm of the modulus of the determinant.
...	optional arguments, currently unused.

Value

a list with elements modulus and sign, which are madness objects.

Note

throws an error for non-square matrices or non-matrix input.
