- - ### Method Detail

    - #### norm

          double norm(weka.core.Instance vec)
               throws Exception

      Calculates the norm of the instance. Only numeric attributes are used.
      Parameters:
        `vec` -
      Returns:
        vector/instance norm
      Throws:
        `Exception`
      Since:
        1.4.0

    - #### normalize

          weka.core.Instance normalize(weka.core.Instance inst)
                                throws Exception

      Returns normalized instance. Only numeric attributes are normalized. If the norm of the vector is 0, then the vector is not normalized.
      Parameters:
        `inst` - -- instance to normalize
      Returns:
      Throws:
        `Exception`
      Since:
