decay
Estimate spectral coefficient decay rates to guide dimension-adaptive refinement.
Specification
Alias: None
Arguments: None
Description
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.
