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

    Note:   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.

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:   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.
