Detailed Description

A local operator for the mass operator (L_2 integral)

\begin{align*} \int_\Omega uv dx \end{align*}

This operator also works for trees of function spaces by applying the L2 operator on the block diagonal.

Constructor & Destructor Documentation

L2()

Dune::PDELab::L2::L2 ( int  intorderadd = 0, double  scaling = 1.0  )

inline

Constructs a new L2 operator.

This constructor creates a new L2 operator.

Parameters

intorderadd	By default, the operator will use the sum of the degrees of the ansatz and test space as its integration order. This parameter gets added to that value and lets you modify the default.
scaling	The output of the operator will be scaled by this value.
