Permute input symbols using a permutation vector


Y = step(H,X)



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 step method forms the output Y, based on the mapping defined by the PermutationVector property as Output(k)=Input(PermutationVector(k)), for k = 1:N, where N is the length of the PermutationVector property. The input X must be a column vector of length N. The data type of X can be numeric, logical, or fixed-point (fi objects). Y has the same data type as X.


obj 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. For more information on changing property values, see System Design in MATLAB Using System Objects.
