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: VBA_UNLtemp.m
    path of file: ./repos/VBA-toolbox/core/unormalizedLikelihood
    
    the code of the file until where you have to start completion: function [posterior,suffStat] = VBA_UNLtemp(y,posterior,suffStat,dim,u,options)
% VB update of the inverse tempterature of un-normalized likelihoods



    
function [posterior,suffStat] = VBA_UNLtemp(y,posterior,suffStat,dim,u,options)
% VB update of the inverse tempterature of un-normalized likelihoods


if options.DisplayWin % Display progress
    try
        STR = 'VB update of the temperature hyperparameter... ';
        set(options.display.hm(1),'string',STR);
        set(options.display.hm(2),'string','0%');
        drawnow
    end
