rc_to_poly (MathScript RT Module Function)
Owning Class: modeling and prediction
Requires: MathScript RT Module
Syntax
a = rc_to_poly(k)
[a, err] = rc_to_poly(k, r0)
Legacy Name: rc2poly
Description
Generates a prediction polynomial from reflection coefficients.
Inputs
| Name | Description |
|---|---|
| k | Specifies the reflection coefficients. |
| r0 | Specifies the zero lag of the autocorrelation sequence. |
Outputs
| Name | Description |
|---|---|
| a | Returns the coefficients of the prediction polynomial. |
| err | Returns the prediction error. |
Examples
r = [1, 3, 2, 4];
n = 3;
[a, err, k] = levinson(r, n);
[aa, ee] = rc_to_poly(k, r(1))
