Class ElementComparative

java.lang.Object
  extended by org.nfunk.jep.function.PostfixMathCommand
      extended by org.nfunk.jep.function.Comparative
          extended by org.lsmp.djep.vectorJep.function.ElementComparative
All Implemented Interfaces:
BinaryOperatorI, PostfixMathCommandI

public class ElementComparative
extends Comparative
implements BinaryOperatorI

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

Method Detail

calcDim

public Dimensions calcDim(Dimensions ldim,
                          Dimensions rdim)
Description copied from interface: BinaryOperatorI
Find the dimensions of this operator when applied to arguments with given dimensions.

Specified by:
calcDim in interface BinaryOperatorI

calcValue

public MatrixValueI calcValue(MatrixValueI res,
                              MatrixValueI lhs,
                              MatrixValueI rhs)
                       throws ParseException
Multiply the inputs element by element putting the results in res.

Specified by:
calcValue in interface BinaryOperatorI
Throws:
ParseException

run

public void run(java.util.Stack inStack)
         throws ParseException
Description copied from class: PostfixMathCommand
Throws an exception because this method should never be called under normal circumstances. Each function should use it's own run() method for evaluating the function. This includes popping off the parameters from the stack, and pushing the result back on the stack.

Specified by:
run in interface PostfixMathCommandI
Overrides:
run in class Comparative
Throws:
ParseException
