void Dune::Fem::MatrixColumnObject< Traits >::axpy ( const JacobianVectorType &  dphi, const JacobianRangeType &  jacobianFactor, const RangeFieldType &  weight = RangeFieldType(1)  )

inline

axpy operation for local matrices

Denoting an entry of the local matrix by \(a_{i,j}\) and the gradients of the base functions by \(\nabla \varphi_i\), this function performs the following operation:

\[ a_{i,j} = a_{i,j} + weight * (jacobianFactor \cdot \nabla\varphi_i( x )) \]

Parameters

[in]	dphi	evaluations of the jacobian of all base functions \(\varphi_i( x )\)
[in]	jacobianFactor	axpy factor
[in]	weight	integration weight for quadrature point (default = 1)
