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: TickMeter.m
    path of file: ./repos/mexopencv/+cv
    
    the code of the file until where you have to start completion: classdef TickMeter < handle
    %TICKMETER  A class to measure passing time
    %
    % The class computes passing time by counting the number of ticks per
    % second. That is, the following code computes the execution time in
    % seconds:
    %
    %     tm = cv.TickMeter();
    %     tm.start();
    %     % do something ...
    %     tm.stop();
    %     disp(tm.TimeSec)
    %
    % It i
    
function t = getTickCount();
            %GETTICKCOUNT  Returns the number of ticks.
            %
            %     t = cv.TickMeter.getTickCount()
            %
            % ## Output
            % * __t__ number of ticks.
            %
            % The function returns the number of ticks after a certain event
            % (for example, when the machine was turned on). It can be used to
            % initialize RNG or to measure a function execution time by
            % reading the tick count before and after the function call.
            %
            % See also: cv.TickMeter.getTickFrequency, cv.TickMeter
            %
            t = TickMeter_(0, 'getTickCount');
        end
