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: PhiSections.m
    path of file: ./repos/mtex/plotting/ODFSections
    
    the code of the file until where you have to start completion: classdef PhiSections < ODFSections

  properties
    Phi
    maxphi1
    maxphi2
    maxPhi
  end
