  - compute
```
double compute(double[] a,
             double[] b)
               throws DimensionMismatchException
```
    Compute the distance between two n-dimensional vectors.
    The two vectors are required to have the same dimension.
    
    Parameters:
    a - the first vector
    b - the second vector
    
    Returns:
    the distance between the two vectors
    
    Throws:
    
    DimensionMismatchException - if the array lengths differ.
