    • norm

      double norm(double[] x)
      Used to compute the norm \( \Vert X \Vert \) in the Gram-Schmidt implementation. If this function is not implemented, the \( L_2 \) norm is used.
      Parameters:
      x - input double vector for which the norm will be computed.
      Returns:
      a double, the value of the norm of x.
