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: pleBestP.m
    path of file: ./repos/d2d/arFramework3/PLE
    
    the code of the file until where you have to start completion: % pleBestP
% 
%   This function can be used to translate a better optimum seen in the
%   profile likelhoods to the model, i.e. to the global variabe 'ar'.
% 
%   It has been written to stop ple.m by hand if a better optimium is seen.
%   After calling this function arFit should be applied to optimize all
%   parameters around the new optimium.
% 
% 
% Example:
% arLoad
% arFit
% arPLEInit
% ple    % after a while, a better optimium occurs -> use
