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: ODF.m
    path of file: ./repos/mtex/ODFAnalysis/@ODF
    
    the code of the file until where you have to start completion: classdef ODF
% This class 
    
function odf = loadobj(s)
      % called by Matlab when an object is loaded from an .mat file
      % this overloaded method ensures compatibility with older MTEX
      % versions
      
      % maybe there is nothing to do
      if isa(s,'SO3Fun'), odf = s; return; end
