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: fundamentalRegionEuler.m
    path of file: ./repos/mtex/geometry/@symmetry
    
    the code of the file until where you have to start completion: function  [maxPhi1,maxPhi,maxPhi2] = fundamentalRegionEuler(cs,ss,varargin)
% get the fundamental region in Euler angles
%
% Syntax
%
%   [maxPhi1,maxPhi,maxPhi2] = fundamentalRegionEuler(cs)

    
function  [maxPhi1,maxPhi,maxPhi2] = fundamentalRegionEuler(cs,ss,varargin)
% get the fundamental region in Euler angles
%
% Syntax
%
%   [maxPhi1,maxPhi,maxPhi2] = fundamentalRegionEuler(cs)
%   [maxPhi1,maxPhi,maxPhi2] = fundamentalRegionEuler(cs,ss)
%
% Input
%  cs - @crystalSymmetry
%  ss - @specimenSymmetry
%
% Output
%  maxPhi1 - maximum Euler angle phi_1
%  maxPhi  - maximum Euler angle Phi
%  maxPhi2 - maximum Euler angle phi_2

  maxPhi1 = 2*pi;
  maxPhi = pi;
  maxPhi2 = 2*pi;
