sgpp::pde::OperationLaplaceModPolyClenshawCurtis::~OperationLaplaceModPolyClenshawCurtis ( )

virtual

Destructor.

Member Function Documentation

◆ mult()

void sgpp::pde::OperationLaplaceModPolyClenshawCurtis::mult	(	sgpp::base::DataVector &	alpha,
		sgpp::base::DataVector &	result
	)

virtual

Implementation of standard matrix multiplication.

Parameters

alpha	DataVector that is multiplied to the matrix
result	DataVector into which the result of multiplication is stored

int nabla phi_i(x) * nabla phi_j(x) dx = sum_k int (dx_k phi_i(x)) * (dx_k phi_j(x)) dx = sum_k int (phi'_{i_k}(x_k) * phi'_{i_k}(x_k) * prod_{l!=k} phi_{i_l}(x_l) * phi_{j_l}(x_l)) dx = sum_k int (phi'_{i_k}(x_k) * phi'_{j_k}(x_k)) dx_k * prod_{l!=k} int (phi_{i_l}(x_l) * phi_{j_l}(x_l)) dx_l

Implements sgpp::base::OperationMatrix.
