Conversion of prediction polynomial to autocorrelation sequence.
Syntax
r = poly2ac(a,efinal)
Description
r = poly2ac(a,efinal)
finds the autocorrelation sequence corresponding to prediction polynomial a and final prediction error efinal. If a(1) is not equal to 1, poly2ac normalizes the prediction polynomial by a(1). a(1) cannot be 0.
