[k, r0] = poly_to_rc(a, err)
Legacy Name: poly2rc
Description
Generates reflection coefficients from a prediction polynomial input.
Inputs
| Name | Description |
|---|---|
| a | Specifies the coefficients of the prediction filter. a is a vector. |
| err | Specifies the prediction error. err is a real number. |
Outputs
| Name | Description |
|---|---|
| k | Returns the reflection coefficients. k is a vector. |
| r0 | Returns the zero lag of the autocorrelation sequence. |
Examples
r = [1, 3, 2, 4];
n = 3;
[a, err, k] = levinson(r, n);
[k, r0] = poly_to_rc(a, err)
