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: mne_rt_client.m
    path of file: ./repos/fieldtrip/external/mne
    
    the code of the file until where you have to start completion: classdef mne_rt_client < handle
    %MNE_RT_CLIENT is a base class for a mne_rt_server real-time connection
    %
    %   This class provides methods for establishing a mne_rt_s
    
function result = init(obj, host, port, numOfRetries) 
            %
            % result = init(obj, host, port, numOfRetries) 
            %
            % Init the connection
            %
            % host          - ip adress of the mne_rt_Server
            % port          - comand port of the mne_rt_Server
            % numOfRetries  - number of connection retries, when a
            %                 connection fails
