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: TesseractSubdivisionTest.m
    path of file: ./repos/libDirectional/lib/tests/util
    
    the code of the file until where you have to start completion: classdef TesseractSubdivisionTest < matlab.unittest.TestCase
   
    properties
    end
    
    methods (Test)
       
    
function testTesseractSubdivisionUnnormalized(testCase)
            for n=0:3
                m = (2^n+1)^4-(2^n-1)^4;
                x = tesseractsubdivision(m-1, false);
                testCase.verifySize(x, [m 4]);
                testCase.verifyLessThanOrEqual(abs(x), ones(m,4)); %inside cube
                testCase.verifyEqual(max(abs(x),[],2), ones(m,1), 'AbsTol', 1E-10); %check on cube surface
                testCase.verifyEqual(sum(x,1), zeros(1,4), 'AbsTol', 1E-10); %check mean zero
                testCase.verifyEqual(x+flipud(x), zeros(m,4), 'AbsTol', 1E-10); %check symmetry
            end
