Owning Class: modeling and prediction
Requires: MathScript RT Module
Syntax
r = poly_to_ac(a, e)
Legacy Name: poly2ac
Description
Generates an autocorrelation sequence from a prediction polynomial input.
Inputs
| Name | Description |
|---|---|
| a | Specifies the prediction polynomial. a is a vector. |
| e | Specifies the final prediction error. e is a real number. |
Outputs
| Name | Description |
|---|---|
| r | Returns the autocorrelation sequence. r is a vector. length(r) equals length(a). |
Examples
a = [1, 9, 7, 6, 8, 9];
e = -3;
r = poly_to_ac(a, e)
