| Description | A primitive, but very fast low-frequency filtering of the vector X is performed. For each point, a weighted average of the point itself and its one or few nearest neighbours is calculated. The argument deg decides how many points are taken into accout. E.g., deg=3 means 3-point smoothing by the formula:
Yi = 0.25 * (2*Xi + Xi−1 + Xi+1)
Higher degrees (5, 7, 9...) of smoothing are achieved internally by repeated 3-point smoothing. deg = 0 or 1 means no smoothing at all; deg = 2 or 3 is interpreted as 3-point smoothing, deg = 4 or 5 as 5-point smoothing, and so on. |
