function R=rc2ac(k,R0) %RC2AC reflection coefficients to autocorrelation sequence. % R = RC2AC(K,R0) returns the autocorrelation sequence, R, based on the % reflection coefficients, K, and the zero lag autocorrelation, R0. % R is a vector that contains the auotcorrelation samples at lags % 0,1,2,...,P, where P is the length of K. % % See also AC2RC, POLY2AC, AC2POLY, POLY2RC, RC2POLY. % References: S.
