将根据50g/s流量输入时的阶跃响应数据所建立的模型，代入其它幅值的输入值，验证模型的一致性。(under 50g/s input flow of step response data the model, Other income generation amplitude of the input value, the certification model of consistency.)

本程序包内用matlab编写数值计算方法中的插值的源代码，包括Newton插值法，拉格朗日插值法，在mainInt.m文件中测试，并与拟合函数进行比较。供学习数值计算的程序员参考。(This program package using matlab numerical method of interpolation of the source code, including the Newton interpolation, Lagrange interpolation method, tested in mainInt.m file, and compare with the fitting function. For learning numerical Programmer s Reference.)

GPS卫星钟差预报模型的精度评定，如：线性拟合模型、带有周期项的线性拟合模型、二次项拟合模型、带有周期项的二次项拟合模型等。(Accuracy Evaluation GPS satellite clock error prediction model, such as: linear fitting model, linear fitting model with periodic term, quadratic fitting model, fitted with a quadratic term cycle models.)

说明：  k均值聚类算法（k-means clustering algorithm）是一种迭代求解的聚类分析算法，其步骤是，预将数据分为K组，则随机选取K个对象作为初始的聚类中心，然后计算每个对象与各个种子聚类中心之间的距离，把每个对象分配给距离它最近的聚类中心。(The k-means clustering algorithm is an iteratively solved clustering algorithm in which the data is pre-divided into K groups, the K objects are randomly selected as the initial clustering center, and then the distance between each object and the seed clustering center is calculated, and each object is assigned to the clustering center closest to it.)
