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: incorporate.m
    path of file: ./repos/Algorithms_MathModels/MATLAB智能算法30个案例分析/chapter12 免疫优化算法在物流配送中心选址中的应用
    
    the code of the file until where you have to start completion: function newindividuals = incorporate(individuals,sizepop,bestindividuals,overbest)
% 将记忆库中抗体加入，形成新种群

    
function newindividuals = incorporate(individuals,sizepop,bestindividuals,overbest)
% 将记忆库中抗体加入，形成新种群
% individuals         input          抗体群
% sizepop             input          抗体数
% bestindividuals     input          记忆库
% overbest            input          记忆库容量

m = sizepop+overbest;
newindividuals = struct('fitness',zeros(1,m), 'concentration',zeros(1,m),'excellence',zeros(1,m),'chrom',[]);

% 遗传操作得到的抗体
for i=1:sizepop
    newindividuals.fitness(i) = individuals.fitness(i);   
    newindividuals.concentration(i) = individuals.concentration(i);   
    newindividuals.excellence(i) = individuals.excellence(i);   
    newindividuals.chrom(i,:) = individuals.chrom(i,:);
