Since Exocortex, NAudio, NWaves and Lomont support radix 2 only, the benchmark uses arrays with sizes that are a power of 2. Follow asked Dec 9, 2011 at 18:28. For instance Gauss-Newton's method where you would use linear regression in each iteration to solve a (overdetermined) system of linear equations, but this would still require some "manual" work with writing Based on v0. Net, but now that I also need to calculate EMA (exponential moving average) or any kind of weighted moving average, I don't find it in Smoothing is the process of removing noise from raw a input signal. ~Mel'nikov \paper Smoothing of Stanley--Reisner type singularities \jour Mat.

The obtained non-linear estimates are compared to the corresponding optimal linear estimates. Commonly, it’s used as a preprocessing step with experimental data, especially spectrometry data because of it’s effectiveness at removing random variation while minimally degrading the signal’s information content. 6, 66–72; Automation and Remote Control, 74:5 (2013), 853–862.
