step

System object: dsp.LPCToLSF
Package: dsp

Convert LPC coefficients to line spectral frequencies

Syntax

LSF = step(H,A)
[..., STATUS] = step(H,A)

Description

LSF = step(H,A) converts the LPC coefficients, A , to line spectral frequencies, LSF, in the range (0 pi). The System object™ operates along the columns of the input A.

[..., STATUS] = step(H,A) also returns the status flag, STATUS, indicating if the current output is valid when the ExceptionOutputPort 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.
