Autocorrelation of * N*-D array

**Library:**DSP System Toolbox / Statistics

The Autocorrelation block computes the autocorrelation
along the first dimension of an * N*-D input array.
The computation can be done in the time domain or frequency domain.
You can specify the domain through the

You can specify the maximum lag for autocorrelation using the **Compute
all non-negative lags** and **Maximum non-negative
lag (less than input length)** parameters.

The block accepts fixed-point signals when you set the **Computation
domain** to `Time`

.
