    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.
