Method Detail

calcDim

public Dimensions calcDim(Dimensions ldim,
                          Dimensions rdim)
                   throws ParseException

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

Throws:

ParseException

calcValue

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

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.

Throws:

ParseException
