System object: dsp.LevinsonSolver
Package: dsp

Reflection coefficients corresponding to columns of input


K = step(levinson,X)
A = step(levinson,X)
[A, K] = step(levinson,X)
[..., P] = step(levinson,X)



Starting in R2016b, instead of using the step method to perform the operation defined by the System object™, you can call the object with arguments, as if it were a function. For example, y = step(obj,x) and y = obj(x) perform equivalent operations.

K = step(levinson,X) returns reflection coefficients K corresponding to the columns of input X. X is typically a column or matrix of autocorrelation coefficients with lag 0 as the first element.

A = step(levinson,X) returns polynomial coefficients A when the AOutputPort property is true and the KOutputPort property is false.

[A, K] = step(levinson,X) returns polynomial coefficients A and reflection coefficients K when both the AOutputPort and KOutputPort properties are true.

[..., P] = step(levinson,X) also returns the error power P when the PredictionErrorOutputPort property is true.


obj specifies the System object on which to run this step method.

The object performs an initialization the first time the step method is executed. This initialization locks nontunable properties (MATLAB) and input specifications, such as dimensions, complexity, and data type of the input data. If you change a nontunable property or an input specification, the System object issues an error. To change nontunable properties or inputs, you must first call the release method to unlock the object.
