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

public class ExteriorProduct
extends PostfixMathCommand
implements BinaryOperatorI

An overloaded operator, either cross product or power. If the arguments are 3D vectors then treat as cross product. Otherwise treet as power.

public ExteriorProduct()
Method Detail

calcDim

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

Specified by:
calcDim in interface BinaryOperatorI
Throws:
ParseException

calcValue

public MatrixValueI calcValue(MatrixValueI res,
                              MatrixValueI lhs,
                              MatrixValueI rhs)
                       throws ParseException
Description copied from interface: BinaryOperatorI
Calculates the value of this operator for given input with results stored in res. res is returned. Using this method is slightly faster than the standard run method as it eliminates the construction of tempoary objects.

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 PostfixMathCommand
Throws:
ParseException

crosspower

public java.lang.Object crosspower(java.lang.Object param1,
                                   java.lang.Object param2)
                            throws ParseException
Throws:
ParseException

exteriorProduct

public java.lang.Object exteriorProduct(MVector lhs,
                                        MVector rhs)
                                 throws ParseException
Throws:
ParseException
