matrixDetDS assign function called by ds.matrixDet

Calculates the determinant of a square matrix A and writes the output to the serverside

matrixDetDS2(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 written to the serverside. 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.
