Detailed Description

template<class B, class Q, bool onb>
struct Dune::LocalL2Interpolation< B, Q, onb >

A local L2 interpolation taking a test basis and a quadrature rule.

This class computes a local interpolation where the coefficients are of the form: c = M^{-1}b

  • M is the mass matrix with respect to the given basis and
  • b = int f phi (where phi are the basis functions). Thus the resulting local function u=c.varphi is defined through the l2 interpolation int u phi = in f phi for all phi in the base function set. The third template argument can be used to specify that the mass matrix is the unit matrix (onb=true).
