step

System object: dsp.CepstralToLPC
Package: dsp

LPC coefficients from column of cepstral coefficients

Syntax

A=step(H,CC)
[A,P]=step(H,CC)

Description

A=step(H,CC) computes the linear prediction coefficients (LPC) coefficients, A , from the columns of cepstral coefficients, CC.

[A,P]=step(H,CC) converts the columns of the cepstral coefficients CC to the LPCs and returns the prediction error power P when the PredictionErrorOutputPort property is true.

    Note:   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.
