%% Reflection Coefficients of Speech Autocorrelation Sequence
% Create an autocorrelation sequence from the MATLAB® speech signal contained in mtlb.mat. Use the Schur algorithm to compute the reflection coefficients of a lattice prediction filter for the sequence.

load mtlb
r = xcorr(mtlb(1:5),'unbiased');
k = schurrc(r(5:end))
