System object: dsp.LevinsonSolver
Reflection coefficients corresponding to columns of input
K = step(H,X)
A = step(H,X)
[A, K] = step(H,X)
[..., P] = step(H,X)
K = step(H,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(H,X) returns polynomial coefficients A when the AOutputPort property is true and the KOutputPort property is false.
[A, K] = step(H,X) returns polynomial coefficients A and reflection coefficients K when both the AOutputPort and KOutputPort properties are true.
[..., P] = step(H,X) also returns the error power P when the PredictionErrorOutputPort property is true.
Note: H 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 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.
