BlendingData<DIM>

BlendingData is basically a collection of DIM-dimensional UniformData<DIM>. Each of the arrays stores either nodal values or scaling function coefficients or wavelet coefficients for a particular uniform grid or trial space. BlendingData is used for the so-called combination technique which allows to extrapolate results of e.g. a numerical quadrature to sparse grids. The member function LevelAdaptiveData<DIM>::Blend() performs the combination of results.
