Owning Class: modeling and prediction
Requires: MathScript RT Module
a = levinson(r)
a = levinson(r, n)
[a, err, k] = levinson(r)
[a, err, k] = levinson(r, n)
Uses Levinson-Durbin recursion to find the coefficients of a p-th all-pole IIR filter.
Name | Description |
---|---|
r | Specifies the deterministic autocorrelation sequence. If r is a matrix, LabVIEW determines the backward filter coefficients column by column. |
n | Specifies the order of the backward filter coefficients. The default is length(r) - 1. |
Name | Description |
---|---|
a | Returns the backward filter coefficients. |
err | Returns the prediction error. |
k | Returns the reflection coefficients. |
The following table lists the support characteristics of this function.
