Method Detail

calcDim

public Dimensions calcDim(Dimensions l,
                          Dimensions r)

Description copied from interface: BinaryOperatorI

Find the dimensions of this operator when applied to arguments with given dimensions.

Specified by:

calcDim in interface BinaryOperatorI

Overrides:

calcDim in class MMultiply

calcValue

public MatrixValueI calcValue(MatrixValueI res,
                              MatrixValueI lhs,
                              MatrixValueI rhs)
                       throws ParseException

calculates the value.

Specified by:

calcValue in interface BinaryOperatorI

Overrides:

calcValue in class MMultiply

Parameters:

res - - results will be stored in this object

lhs - - lhs value

rhs - - rhs value

Returns:

res

Throws:

ParseException

calcValue

public Scaler calcValue(Scaler res,
                        MVector lhs,
                        MVector rhs)
                 throws ParseException

Throws:

ParseException

run

public void run(java.util.Stack stack)
         throws ParseException

Description copied from interface: PostfixMathCommandI

Run the function on the stack. Pops the arguments from the stack, and pushes the result on the top of the stack.

Specified by:

run in interface PostfixMathCommandI

Overrides:

run in class MMultiply

Throws:

ParseException

dot

public java.lang.Object dot(java.lang.Object param1,
                            java.lang.Object param2)
                     throws ParseException

returns param1 . param2. Defaults to scaler mult if parameters are not vectors.

Throws:

ParseException

dot

public java.lang.Object dot(MVector lhs,
                            MVector rhs)
                     throws ParseException

returns lhs . rhs

Throws:

ParseException
