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: LHSintegrator_Advection.m
    path of file: ./repos/Swan/Topology Optimization/Operators/Integrator
    
    the code of the file until where you have to start completion: classdef LHSintegrator_Advection < handle

    properties (Access = private)
        mesh
        test, trial
        b
        rho
        quadrature
        quadratureOrder
    end

    methods (Access = public)

        function obj = LHSintegrator_Advection(cParams)
            obj.init(cParams);
            obj.createQuadrature();
        end

        function 
    
function [CX,CY,DX,DY,EX,EY,Kxx,Kxy,Kyy,Mxx,Mxy,Myy,Mrho] = compute(obj)
            [CX,CY,DX,DY,EX,EY,Kxx,Kxy,Kyy,Mxx,Mxy,Myy,Mrho] = obj.computeElementalLHS();
            CX = obj.assembleMatrix(CX);
            CY = obj.assembleMatrix(CY);
            DX = obj.assembleMatrix(DX);
            DY = obj.assembleMatrix(DY);
            EX = obj.assembleMatrix(EX);
            EY = obj.assembleMatrix(EY);
            Kxx = obj.assembleMatrix(Kxx);
            Kxy = obj.assembleMatrix(Kxy);
            Kyy = obj.assembleMatrix(Kyy);
            Mxx = obj.assembleMatrix(Mxx);
            Mxy = obj.assembleMatrix(Mxy);
            Myy = obj.assembleMatrix(Myy);
            Mrho = obj.assembleMatrix(Mrho);
        end
