    %% Autocorrelation Of a Number Sequence
%%
% *Note*: This example runs only in R2016b or later. If you are using an
% earlier release, replace each call to the function with the equivalent
% |step| syntax. For example, myObject(x) becomes step(myObject,x).

%%
hac1 = dsp.Autocorrelator;
% x is a column vector
x = [1:100]';
y = hac1(x);
