Matrix (version 0.3-26)

det: Calculate the Determinant of a Matrix

Description

determinant calculates the determinant (or its logarithm) of a matrix

Usage

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

Arguments

x

numeric matrix.

logarithm

logical. When TRUE, the default, the logarithm of the determinant is returned. When FALSE, the determinant of x is returned.

...

further arguments passed to or from other methods.

Value

• determinant return a list with two elements
  • modulus
  {a numeric value. The modulus (absolute value) of the determinant or the logarithm of the modulus. The value of the logarithm argument is included as an attribute.}
• sign
  a numeric value, which is $\pm 1$ according to whether the determinant is positive or negative.

Details

determinant is a generic function with special methods for different types of matrices or decompositions. Use methods("determinant") to list all the methods for the determinant generic.
