Estimate spectral coefficient decay rates to guide dimension-adaptive refinement.
Alias: none
Argument(s): none
Estimate spectral coefficient decay rates from a rate estimation technique similar to Richardson extrapolation. These decay rates are used to guide dimension-adaptive refinement, where slower decay rates result in higher dimension preference.
