Adaptive-degree polynomial filter for data - Adaptive-degree polynomial filter (Savitzky-Golay Filter) for data differentiation (1st derivative). Commonly, the degree of the fitting polynomial for the Savitzky-Golay filter is fixed. However, the polynomial degree can vary according to the sum of squares of fitting residuals and the statistical testing to obtain the adaptive-degree polynomial filter. This function obtains the polynomial degree (output: polynomial_degree) selected in the adaptive-degree polynomial filter (Savitzky-Golay filter)for the data subset of length 2M 1 (intput: data_frame).Usage:Run Pkmi_Calculate first to obtain the numerical table of gram polynomials so as to accelerate the calculation. And See the demo of above-mentionded function of data smoothing for reference. Requirements: · MATLAB Release: R13SP1
