ac2rc (MathScript Function) (Windows, Not in Base Package)
Member of the modeling and prediction class.
Syntax
[k, r0] = ac2rc(r)
Description
Generates a sequence of reflection coefficients from an autocorrelation sequence input. LabVIEW then can use the coefficients in k to design a lattice prediction filter. This filter generates an autocorrelation sequence similar to the original sequence r.
Inputs
| Name | Description |
| r | Specifies the autocorrelation sequence. r is a vector. |
Outputs
| Name | Description |
| k | Returns the reflection coefficients. length(k) equals length(r) - 1. |
| r0 | Returns the zero lag of the autocorrelation sequence. |
Examples
r = [0.5, 0, -1.75, 3, -2];
[k, r0] = ac2rc(r)
