evalPartialDerivative() [1/2]

void sgpp::base::OperationEvalPartialDerivativeWaveletNaive::evalPartialDerivative ( const DataMatrix &  alpha, const DataVector &  point, size_t  derivDim, DataVector &  value, DataVector &  partialDerivative  )

overridevirtual

Parameters

	alpha	coefficient matrix (each column is a coefficient vector)
	point	evaluation point
	derivDim	dimension in which the partial derivative should be taken (0, ..., d-1)
[out]	value	values of the linear combination
[out]	partialDerivative	values of the partial derivatives of the linear combination (the j-th entry corresponds to the j-th column of alpha)

Reimplemented from sgpp::base::OperationEvalPartialDerivative.
