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. At present none are used. Previous versions of det allowed an optional method argument. This argument will be ignored but will not produce an error.

Value

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

Note

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