Method Detail

calcDim

Dimensions calcDim(Dimensions ldim)

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

calcValue

MatrixValueI calcValue(MatrixValueI res,
                       MatrixValueI lhs)
                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
