Detailed Description

template<int dim, int fe_degree, int n_q_points_1d = fe_degree + 1, int n_components = 1, typename VectorType = LinearAlgebra::distributed::Vector<double>, typename VectorizedArrayType = VectorizedArray<typename VectorType::value_type>>
class MatrixFreeOperators::MassOperator< dim, fe_degree, n_q_points_1d, n_components, VectorType, VectorizedArrayType >

This class implements the operation of the action of a mass matrix.

Note that this class only supports the non-blocked vector variant of the Base operator because only a single FEEvaluation object is used in the apply function.
