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: NumericalHomogenizerDataBase.m
    path of file: ./repos/Swan/Topology Optimization/Homogenization/Sources/Homogenizer/NumericalHomogenizer
    
    the code of the file until where you have to start completion: classdef NumericalHomogenizerDataBase < handle
    
    properties (SetAccess = private, GetAccess = public)
        dataBase
    end
    
    properties (Access = private)
        femFileName
    end
    
    methods (Access = public)
        
        function obj = NumericalHomogenizerDataBase(femFileName)
            obj.femFileName = femFileName;
            obj.createDataBase();
        end
 
    
function createDataBase(obj)
            d = obj.createNumericalHomogenizerDataBase();
            d.levelSetDataBase       = obj.createLevelSetDataBase();
            d.materialInterpDataBase = obj.createMaterialInterpDataBase();
            d.materialDataBase       = obj.createMaterialDataBase();
            d.volumeShFuncDataBase   = obj.createShVolumeDataBase(d);
            obj.dataBase = d;
        end
        
        function d = createNumericalHomogenizerDataBase(obj)
            edt = 'ElementalDensityCreatorByLevelSetCreator';
            d.elementDensityCreatorType = edt;
            d.outFileName  = 'NumericalHomogenizer';
            d.testName     = obj.femFileName;
            d.print = false;
            d.iter  = 0;
            d.pdim = '2D';
        end
