System object: dsp.LSFToLPC
Package: dsp

Convert input line spectral frequencies to linear prediction coefficients


A = step(H,LSF)


    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,LSF) converts the input line spectral frequencies, (LSF), in the range (0,pi), LSF , to linear prediction coefficients, A. The input can be a vector or a matrix, where each column of the matrix is treated as a separate channel.

    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.
