System object: comm.MatrixInterleaver
Package: comm

Permute input symbols using permutation matrix


Y = step(H,X)


    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) permutes input sequence, X, and returns interleaved sequence, Y. The object fills a permutation matrix with the input symbols row by row and outputs the matrix contents column by column. The input X must be a column vector of length NumRows×NumColumns and the data type can be numeric, logical, or fixed-point (fi objects). Y has the same data type as X.

    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.
