step

System object: comm.BCHEncoder
Package: comm

Encode data using a BCH encoder

Syntax

Y = step(H,X)

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.

Y = step(H,X) encodes input binary data, X, using a (CodewordLength,MessageLength) BCH encoder with the corresponding narrow-sense generator polynomial and returns the result in vector Y. The input and output length of the step function equal the values listed in the table in Input and Output Signal Lengths in BCH and RS System Objects.

    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.
