@Deprecated
public class PermutationMatrixWrapper
extends PackageFunction

Wrapper class for Sorting and Creating of a Permutation Matrix Sort single-column matrix and produce a permutation matrix. Pre-multiplying the input matrix with the permutation matrix produces a sorted matrix. A permutation matrix is a matrix where each row and each column as exactly one 1: To From 1 Input: (n x 1)-matrix, and true/false for sorting in descending order Output: (n x n)- matrix permutation_matrix= externalFunction(Matrix[Double] A, Boolean desc) return (Matrix[Double] P) implemented in (classname="org.apache.sysml.udf.lib.PermutationMatrixWrapper" ,exectype="mem"); A = read( "Data/A.mtx"); P = permutation_matrix( A[,2], false); B = P %*% A
