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: cal_gameutility.m
    path of file: ./repos/Path-Selection-and-Rate-allocation-in-Self-backhauled-mmWave-Networks
    
    the code of the file until where you have to start completion: function [ gameutility_observe ] = cal_gameutility( networkqueue )
global N_SubF % number of each subflows for each flow, assume that each flow is divided equally
global N_BSs % the number of SC BSs
global N_Flow % number of flows 
global N_Actions % The number of actions : Each user is assumed to choose two paths among 4 paths, then 

% Access to the data
% indicator_bs = zeros(N_Flow,N_BSs+1, N_SubF);
% 
pre_queueBS = ones(N_BSs+1,1);
pre_servedrate = 1000*ones(N_Flow,N_SubF);
pre_queueRoute = ones(N_SubF,1);

% 
gameutility_observe = ones(N_Flow,N_Actions);

gameutility_by_route = ones(N_Flow,N_SubF); % the gain for each route

% 4 main routes
Route(1).R = [1 2 3];
Route(2).R = [1 4 5];
