%% Compute Polynomial Coefficients %% % *Note*: This example runs only in R2016b or later. If you are using an % earlier release, replace each call to the function with the equivalent % |step| syntax. For example, myObject(x) becomes step(myObject,x). %% % Use the Levinson solver to compute polynomial coefficients from % autocorrelation coefficients. hlevinson = dsp.LevinsonSolver; hlevinson.AOutputPort = true; hlevinson.KOutputPort = false; x = (1:100)'; hac = dsp.Autocorrelator(... 'MaximumLagSource', 'Property', ... 'MaximumLag', 10); a = hac(x); c = hlevinson(a); % Compute polynomial coefficients
