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.

ExteriorProduct
public ExteriorProduct()
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:
