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: ProductComputerOutputCreator.m
    path of file: ./repos/Swan/Topology Optimization/Homogenization/Sources/ProductComputer
    
    the code of the file until where you have to start completion: classdef ProductComputerOutputCreator < handle
    
    properties (Access = private)
        fourthOrder
        secondOrder
        secondOrderOut
    end
    
    methods (Access = public)
        
        function obj = ProductComputerOutputCreator(C,e)
            obj.in
    
function init(obj,C,e)
            obj.fourthOrder = C;
            obj.secondOrder = e;            
        end
        
        function createSecondOrderOut(obj)
            
            if obj.isTensor()
                if obj.is3D()
                    if obj.isStress()
                        s = Stress3DTensor;
                    elseif obj.isStrain()
                        s = Strain3DTensor;
                    end
                elseif obj.isPlaneStress()
                    if obj.isStress()
                        s = StressPlaneStressTensor;
                    elseif obj.isStrain()
                        s = StrainPlaneStressTensor;
                    end
                end
            elseif obj.isVoigt()
                if obj.is3D()
