You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: Ellipsoid.m
    path of file: ./repos/ott/+ott/+shapes
    
    the code of the file until where you have to start completion: classdef Ellipsoid < ott.shapes.StarShape & ott.shapes.AxisymShape
%Ellipsoid a simple ellipsoid shape
%
% properties:
%   a         % x-axis scaling
%   b         % y-axis scaling
%   c         % z-axis scaling

% This file is part of the opti
    
function shape = Ellipsoid(a, b, c)
      % ELLIPSOID construct a new ellipsoid
      %
      % ELLIPSOID(a, b, c) or ELLIPSOID([a, b, c]) specifies the
      % scaling in the x, y and z directions.

      shape = shape@ott.shapes.StarShape();

      if nargin == 1
        shape.a = a(1);
        shape.b = a(2);
        shape.c = a(3);
      else
        shape.a = a;
        shape.b = b;
        shape.c = c;
      end
