# iir_yulewalker

Version:

Uses the modified Yule-Walker method to create an IIR filter.

## Syntax

[x, y] = iir_yulewalker(n, f, a)
Legacy name: yulewalk

## n

Filter order.

## f

Vector of frequency points. f is a real vector of non-descending values in the interval [0, 1]. 1 represents the Nyquist frequency.

## a

Magnitudes of the filter at the frequency points in f. length(a) must equal length(f).

## x

Forward coefficients of the IIR filter. The length of x equals n + 1.

## y

Backward coefficients of the IIR filter. The length of y equals n + 1.

f0 = [0, 0.2, 0.4, 1];
a0 = [1, 1, 0, 0];
[x0, y0] = iir_yulewalker(8, f0, a0);
