det: det

In RBigData/pbdDMAT: 'pbdR' Distributed Matrix Methods

Description

Calculate the determinant via LU decomposition.

Usage

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

## S4 method for signature 'ddmatrix'
det(x, ...)

Arguments

x	numeric distributed matrices.
logarithm	Should the logarithm of the modulus be returned?
...	Ignored.

Details

Regardless of the value of logarithm, the determinant is calculated by adding the log of the diagonal of U (separately tracking the sign via the pivot matrix).

Value

The determinant (via det()) or an object of class det (via determinant()).
