poly2ac

Convert prediction polynomial to autocorrelation sequence.

- - -

Calling Sequence

R = poly2ac(a,efinal)

- -

Parameters

a: -: input prediction polynomial with 1st element 1 (if not, poly2ac normalizes it to 1 before proceeding).
efinal: -: input prediction error
r: -: output autocorrelation sequence

- -

Description

This function obtains the underlying autocorrelation sequence that would best fit a linear prediction filter described by the -denominator polynomial and the numerator scaling. The filter is H(z) = efinal/(a(1) + a(2) x z a(3) x z^2 ... a(n) x z^n-1)

- -

Examples

a = [1.0000 0.4288 0.76 0.0404 -0.02];
-efinal = 0.2;           // Step prediction error
-r = poly2ac(a,efinal)   // Autocorrelation sequence
