Class ElementComparative

java.lang.Object

org.nfunk.jep.function.PostfixMathCommand

org.nfunk.jep.function.Comparative

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(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
