Package org.apache.sysds.lops

Class Ctable

java.lang.Object

org.apache.sysds.lops.Lop

org.apache.sysds.lops.Ctable

public class Ctable
extends Lop

Lop to perform ternary operation. All inputs must be matrices or vectors. For example, this lop is used in evaluating A = ctable(B,C,W) Currently, this lop is used only in case of CTABLE functionality.
