Member of the modeling and prediction class.

Syntax

[a, e, k] = aryule(x, n)

[a, e] = aryule(x, n)

a = aryule(x, n)

Description

Uses the Yule-Walker method to estimate autoregressive (AR) model parameters.

Examples

Inputs

Name	Description
x	Specifies the input signal. x is a vector.
n	Specifies the order of the AR model. n is a positive integer.

Outputs

Name	Description
a	Returns the model coefficients. a is a vector.
e	Returns the final prediction error. e is a real number.
k	Returns the reflection coefficients. k is a vector.

Examples

x = [7, 9, 2, 0.5, 6, 10];
n = 2;
[a, e, k] = aryule(x, n)
