    `double` | `compute(double[] a, double[] b)` Compute the distance between two n-dimensional vectors.

- - ### Method Detail

    - #### compute

          double compute(double[] a,
                       double[] b)

      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
