R Documentation

matrixDetDS aggregate function called by ds.matrixDet.report

Description

Calculates the determinant of a square matrix A and returns the output to the clientside

Usage

matrixDetDS1(M1.name = NULL, logarithm)

Arguments

M1.name	A character string specifying the name of the matrix for which determinant to be calculated
logarithm	logical. Default is FALSE, which returns the determinant itself, TRUE returns the logarithm of the modulus of the determinant.

Details

Calculates the determinant of a square matrix (for additional information see help for det function in native R). This operation is only possible if the number of columns and rows of A are the same.

Value

Output is the determinant of the matrix identified by argument <M1> which is returned to the clientside. For more details see help for ds.matrixDet
