ac_to_poly (MathScript RT Module Function)
Owning Class: modeling and prediction
Requires: MathScript RT Module
Syntax
[a, e] = ac_to_poly(r)
Legacy Name: ac2poly
Description
Generates a prediction polynomial from an autocorrelation sequence input.
Inputs
| Name | Description |
|---|---|
| r | Specifies the autocorrelation sequence. r is a vector. |
Outputs
| Name | Description |
|---|---|
| a | Returns the prediction polynomial. length(a) equals length(r). |
| e | Returns the final prediction error. e is a real number. |
Examples
r = [0.5, 0, -1.75, 3, -2, 0.3];
[a, e] = ac_to_poly(r)
