算法笔记这本书里的部分题目的答案，通过编译且结果正确(The answers to some of the questions in this book are compiled and the results are correct)

This is a phase field simulation example to simulate the segeration of two phase flow.

进销存管理系统，企业的进销存管理系统。包含系统功能模块，全县管理，(Inventory management system, inventory management system. Contains the system function modules, the county,)

这些代码是有关数字图像处理的一些算法，大家有需要的，可以在里面找些与自己相关的(These codes are some of the digital image processing algorithms, we need, in which you can find some with their associated)

传统的五子棋小游戏，没有做界面设计，很丑，不过大家看逻辑就好了，哈哈   写的逻辑还是很简单的。把这个游戏改成局域网对决的游戏后   会继续上传的最近很闲  想做无聊小游戏的集合   大家有想法可以交流一下

stc12c5a60s2单片机采集心电传感器的电压信号，并在lcd12864上显示心电数字。 误差特别小。(A voltage signal STC12C5A60S2 singlechip collects the ECG sensor, and display of ECG digital in lcd12864. Especially small error.)

USACO第10题，Marry乳业从一些奶农手中采购牛奶，并且每一位奶农为乳制品加工企业提供的价格是不同的。此外，就像每头奶牛每天只能挤出固定数量的奶，每位奶农每天能提供的牛奶数量是一定的。每天Marry乳业可以从奶农手中采购到小于或者等于奶农最大产量的整数数量的牛奶。 给出Marry乳业每天对牛奶的需求量，还有每位奶农提供的牛奶单价和产量。计算采购足够数量的牛奶所需的最小花费。 (Give the requirement of milk and the amount that they offer.)

功能非常强大的计算器，单片机飞思卡尔LCD屏幕显示，可以完成加减乘除还有括号运算(Very powerful calculator microcontroller Freescale LCD screen display, the completion of the addition, subtraction there brackets operator)

利用此函数可以在最小二乘意义上解决非线性曲线拟合（数据 拟合）问题。也就是说，给定输入数据xdata，以及观测的输出数据ydata，找到系数x，使 得函数F(x，xdata)能够最好的拟合向量值(MLS method not only can be applied for the purpose of curve (or surface) fitting, but also curve (or surface) interpolation when compactly supported singular weighted function was used. The effective measure has been applied to eliminate singularity in MLS interpolation. In addition, the bad fitting or interpolation accuracy near the boundary was improved. )

说明：  Use the asp function 用asp函数(Asp function for Use the asp function)
