static NaNTransformer createNaNTransformer(NaNPolicy nanPolicy,
                                           boolean copy)
```
    Creates a NaNTransformer based on the nanPolicy and data copy policy.
    The transformer is thread-safe.
    
    Parameters:
    
    nanPolicy - NaN policy.
    
    copy - Set to true to use a copy of the data.
    
    Returns:
    
    the transformer
  - copy
```
static double[] copy(double[] data,
                     int from,
                     int to)
```
    Copy the specified range of data.
    This is a simplification of Arrays#copyOfRange(double[], int, int) and does not support range checks or padding of the original input to a longer output.
    
    Parameters:
    
    data - Values.
    
    from - Inclusive start of the range.
    
    to - Exclusive end of the range.
    
    Returns:
    
    the copy
