org.nfunk.jep.function.Divide

org.lsmp.djep.vectorJep.function.ElementDivide

All Implemented Interfaces:

BinaryOperatorI, PostfixMathCommandI

public class ElementDivide
extends Divide
implements BinaryOperatorI

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