Detailed Description

template<class F = concepts::Real>
class aglowav::Est04< F >

Error estimator for the constant space.

The refinement decision is made accordingly to the wavelet coefficients of the agglomerated wavelet space based on the constant space. Refinement: refinement if the weighted $l_2$ norm of the wavelet coefficients on the way from the root to a leaf is larger than the weighted $l_2$ norm of all wavelet coefficients times the trshld. The weights are $2^ls$ for $l$ the level and $s$ the regularity.

Parameters:

F	Field (Real or Cmplx)
