Computes fractional derivatives based features from input data using the Grunwald-Letnikov estimation of order alpha for input function on a regular gird with spacing h. As an input can be single vector or two paired vectors (e.g. handwriting signal). In case of single input vector velocity, acceleration and jerk are calculated for selected alpha range. In case of two paired vectors input the same kinematic features are provided included their horizontal and vertical characteristics.
