我这里有个数学模型，每一块的实现都写成.m文件了，怎么将它们全部导入MATLAB然后只运行主程序就可以？谢谢
主程序如下

% estimate_pareto_nbd.m
%
% Script to estimate the Pareto/NBD parameters
% *** requires the Optimization Toolbox ***
% *** assumes the script load_data.m has be run ***

lb = .0001 * ones(1,4);
ub = 20 * ones(1,4);

initial = ones(1,4);

[params ll] = fmincon('pareto_nbd_ll',initial,[],[],[],[],lb,ub)
compute_pactive(params)
