org.nfunk.jep.function.Multiply

org.lsmp.djep.vectorJep.function.ElementMultiply

All Implemented Interfaces:

NaryOperatorI, PostfixMathCommandI

public class ElementMultiply
extends Multiply
implements NaryOperatorI

Multiplies any number of Vectors or Matricies element by element. TODO could be much more efficient when called through run.
