Perform one step of the Durbin-Levinson algorithm..
durbinlevinson (C); durbinlevinson (C, OLDPHI); durbinlevinson (C, OLDPHI, OLDV);
The vector C specifies the autocovariances '[gamma_0, ..., gamma_t]' from lag 0 to T.
It specifies the coefficients based on C(T-1).
It specifies the corresponding error.
This is an Octave function. Perform one step of the Durbin-Levinson. If OLDPHI and OLDV are omitted, all steps from 1 to T of the algorithm are performed.
