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: simulationParameters.m
    path of file: ./repos/5G_based_System_level_Integrated_Sensing_and_Communication_Simulator/+parameters
    
    the code of the file until where you have to start completion: classdef simulationParameters
    %SIMULATIONPARAMETERS main class where all simulation parameters are defined
    %   
    
    properties
        % simulation time parameters
        time

        % sim
    
function obj = simulationParameters()
            %SIMULATIONPARAMETERS
            % class constructor that sets default values
            % The class constructor initializes the class and the attached
            % parmeter classes. Geometry and network element related
            % parameters are stored in containers.

            % initialize attached classes
            obj.time = parameters.time;
            obj.roi  = parameters.regionOfInterest.region;
            obj.log  = parameters.log;

            % initialize map containers
            obj.cityParameters       = containers.Map();
            obj.bsParameters         = containers.Map();
            obj.ueParameters         = containers.Map();
            obj.targetParameters     = containers.Map();
            obj.schedulingParameters = containers.Map();
            obj.trafficParameters    = containers.Map();
            obj.pathLossParameters   = containers.Map();
            obj.comChannelParameters = containers.Map();
            obj.senChannelParameters = containers.Map();
        end
