public AutoCorrelation()
```
- Method Detail
  - bruteForce
```
public static double[] bruteForce(double[] x)
```
    This is a "wrapped" signal processing-style autocorrelation. For "true" autocorrelation, the data must be zero padded.
    
    Parameters:
    
    x - the sigal, must be even length
    
    Returns:
    
    the autocorrelation
  - fft
```
public static double[] fft(double[] x,
                           boolean normalize)
```
    Uses FFT to perform autocorrelation.
    
    Parameters:
    
    x - the sigal, must be even length
    
    normalize - whether to normalize the output
    
    Returns:
    
    the autocorrelation
  - getTechnicalInformation
```
public static TechnicalInformation getTechnicalInformation()
```
    Returns technical information on autocorrelation.
    
    Returns:
    
    the technical information
