Function File: a = ac2poly (r)

Function File: [a, e] = ac2poly (r)

Convert autocorrelation sequence to prediction polynomial.

Compute the prediction filter coefficients a from the autocorrelation sequence r using the Levinson-Durbin recursion. The second optional output e returns the final prediction error power.

This function directly calls levinson.
