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: dpli_function.m
    path of file: ./repos/EEGapp/EEGapp/Main/Analysis Techniques
    
    the code of the file until where you have to start completion: function errors = dpli_function(EEG,dpli_prp,workingDirectory,orderType,newOrder)
    %This function is called by the main function when the dPLI is selected
    %and the launch analysis button is pressed

    %Create waitbar and initialize its parameters
    h = waitbar(0,'Please wait...','Name',sprintf('dPli Analysis'));
    
try
    errors = 0;    
    settings = evalin('base','settings');
    full_bp = sett
    
function [] = topofunction(varargin)
%TOPOFUNCTION Summary of this function goes here
%   Detailed explanation goes here
    S = varargin{3};  % Get the structure.
    s = varargin{5};
    current_EEG=varargin{4};
    
F = get(S.fh,'currentpoint');  % The current point w.r.t the figure.
% Figure out of the current point is over the axes or not -> logicals.
tf1 = S.AXP(1) <= F(1) && F(1) <= S.AXP(1) + S.AXP(3);
tf2 = S.AXP(2) <= F(2) && F(2) <= S.AXP(2) + S.AXP(4);

if tf1 && tf2
    % Calculate the current point w.r.t. the axes.
    Cx =  ceil(S.XLM(1) + (F(1)-S.AXP(1)).*(S.DFX/S.AXP(3)));
    Cy =  ceil(S.YLM(1) + (F(2)-S.AXP(2)).*(S.DFY/S.AXP(4)));
    Cy = current_EEG.nbchan - Cy + 1;
