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: ShFunc_ComplianceComparison_constraint.m
    path of file: ./repos/Swan/Topology Optimization/Shape Functions
    
    the code of the file until where you have to start completion: classdef ShFunc_ComplianceComparison_constraint < ShFunWithElasticPdes
    
    properties (Access = private)
        compliance
        fieldToPrint
        adjointProblem
        comparisonComplianceFrac = 4.7
    end
    
    methods (Access = public)
        
        function obj = ShFunc_ComplianceComparison_constraint(cParams)
            cParams.filterParams.quadra
    
function computeGradientValue(obj)
            phy = obj.physicalProblem;
            ep    = phy.variables.strain;
            ngaus  = size(ep,1);
            nstre  = size(ep,2);
            nelem  = size(ep,3);
            g = zeros(nelem,ngaus,obj.nVariables);
            for igaus = 1:ngaus
                for istre = 1:nstre
                    for jstre = 1:nstre
                        eu_i = squeeze(ep(igaus,istre,:));
                        ep_j = squeeze(ep(igaus,jstre,:));
                        for ivar = 1:obj.nVariables
                            dCij = squeeze(obj.homogenizedVariablesComputer.dC(istre,jstre,ivar,:,igaus));
                            g(:,igaus,ivar) = g(:,igaus,ivar) + (-eu_i.*dCij.*ep_j);
