Deinterleave input symbols using permutation matrix


Y = step(H,X)


Y = step(H,X) restores the original ordering of the sequence, X, that was interleaved using a block interleaver. The object fills a permutation matrix with the input symbols column by column and outputs the matrix contents row by row in the output, Y. The input X must be a column vector of length equal to NumRows×NumColumns. The data type for X 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.
