matrixDetDS aggregate function called by ds.matrixDet.report

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

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.

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

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.
