直接修改注册表，改变环境变量，JDK安装的时候可以用这个-Directly modify the registry to change the environment variables, JDK installation time can use this

Start with the runlocalization track.m which is the entrance function to your lab. This function reads two les determined by simoutle and maple input arguments which contain information about sensor readings and the map of the environment respectively, runs a loop for all the sensor readings and calls the ekf localize.m to perform one iteration of EKF localization on the readings and plots the estimation(red)/ground truth(green) and odometry(blue) information.-This lab consists of two parts: 1. A preparatory case study with a standard Kalman lter where you learn more about the behavior of the Kalman lter. Very little extra code is needed. 2. The main lab 1 problem in which you need to complete an implementation of an Extended Kalman lter based robot localization.

基于Android2.2.2版本，Android应用源码高仿微信5.2内测版UI项目，内含微信的四个主要界面，并且包含Android的四大组件中的内容，特别使用到了Fargment组件，值得一提的是该项目特别适合一些Android的初学者，对他们理解这些急促问题提供很大帮助

控件的应用，学习的好帮手！这是 能确定系统当前时间，和程序运行的时间的一个 简单源代码。正因为简单 所以 初学者 可以用得着-Control application, learning a good helper! This system is able to determine the current time, and the running time by a simple source code. Precisely because so beginners can simply worthwhile

此程序是一个简单的代码语法分析程序,检验程序是否符合语法规则-This procedure code is a simple grammar analysis program, inspection procedures are in line with the rules of grammar

这是一个演示使用VB对USB-HID设备进行数据读取写入的通讯示例。可以遍历所有USB设备，由于没有类似调试设备，这个源代码没有测试，但里面的一些API函数可以让大家喜欢研究USB通讯开发的网友提供些帮助，这个代码转载与另外一个网站，如果作者看到有更完善的源代码可以发来更新下，感谢作者。-This is a demonstration using VB on the USB-HID device to read data written communication example. You can traverse all the USB devices, because no such test equipment, the source code is not tested, but inside some of the API functions will allow everyone likes USB communication development User research provide some help, this code is reproduced with another Web site to see if the author have a more complete source code can be made to update the next, thanks author.
