Owning Class: modeling and prediction

Requires: MathScript RT Module

Syntax

r = rc_to_ac(k, r0)

Legacy Name: rc2ac

Description

Generates an autocorrelation sequence from an input sequence of reflection coefficients. LabVIEW uses the rc_to_poly function and Levinson approximation to generate the autocorrelation coefficients in r.

Examples

Inputs

Name Description
k Specifies the reflection coefficients.
r0 Specifies the zero lag of the autocorrelation sequence.

Outputs

Name Description
r Returns the autocorrelation sequence.

Details

The following table lists the support characteristics of this function.

Supported in the LabVIEW Run-Time Engine Yes
Supported on RT targets Yes
Suitable for bounded execution times on RT Not characterized

Examples

r = [1, 3, 2, 4];
n = 3;
[a, err, k] = levinson(r, n);
rr = rc_to_ac(k, r(1))
