说明：  各种最小二乘法案例，对数学建模有一定帮助(Various cases of least square method)

MSP430F147,ST7920A,片上AD，通过uart与上位机通信，上位机程序采用VB编写，另外单片机采样数据通过EEPROM保存。(MSP430F147, ST7920A, chip AD, through the uart communicat with PC, PC s programme finished by VB, and sampling data preserved in EEPROM.)

这是一份tex文档，对于写论文很有帮助,希望要写论文的小伙伴们有缘看见。(A piece of document)

说明：  格子玻尔兹曼方程基于格子Boltzmann方法开源可视化软件的源代码(The source code of open source visualization software based on lattice Boltzmann method has high practical value.)

gps tracking system in java.it receives and decodes nmea sentences.

本程序可以用来简单求取数据的（rmse）均方根误差(Root Mean Square Error)

抓图小工具REV 3.0 可独立批量抓图 新增批量抓图功能，带更新图片功能，可设置时间间隔、抓取数量、信息提示、放大镜功能、方向键微调功能。 批量抓图技巧： 针对网页验证码需要点击更新再抓取的，勾选[点击更新图片]，鼠标拖动[坐标获取]的右边图形移动到需要点击的地方自动获取坐标，设置时间间隔，设置抓取数量，点击批量抓图按钮，完成！ 如果不需要点击更新不勾选[点击更新图片]即可 本程序可辅助OCR识别，图形识别与自动控制(Grab a small tool independently REV 3.0 New Batch Capture Batch Capture feature, with updated picture functions, you can set time interval, the number of crawling, information, tips, a magnifying glass function, the arrow keys to fine-tune the functionality. Batch Capture techniques: code for web pages need to click update and then to crawl, check [click Update Photo], drag the mouse [coordinates to obtain] the right of the graph need to click where to move to automatic acquisition coordinates, set the time interval, set the grab the number, click on Batch Capture button to complete! If you do not click the update does not check the [Click the Update Photo] can this program can assist OCR recognition, pattern recognition and automatic control)

通过geturl、posturl来与http进行交互并操作(Interact and operate with HTTP through geturl and posturl)

说明：  K近邻算法。(k-Nearest Neighbor，KNN)，是一个理论上比较成熟的方法，也是最简单的机器学习算法之一。该方法的思路是：在特征空间中，如果一个样本附近的k个最近(即特征空间中最邻近)样本的大多数属于某一个类别，则该样本也属于这个类别。(K-nearest neighbor algorithm. K-nearest neighbor (KNN) is a mature method in theory and one of the simplest machine learning algorithms. The idea of this method is: in the feature space, if most of the k nearest (i.e. the nearest) samples near a sample belong to a certain category, then the sample also belongs to this category.)

四川大学vb课程的作业，包括了visualbasic程序设计教程这本书上的课后习题部分源码(Sichuan University vb program operations, including visualbasic programming tutorial this book is part of the source on the after-school exercise)
