万年历

说明：  一种用于结构光测量系统中的实现对投影仪的标定过程(Realizing the Calibration Process of Projector)

说明：  taskmgr就是任务管理器的源码也许好多人都有了(Taskmgr is the source code for the task manager. Maybe a lot of people have it.)

此代码为红外遥控密码锁代码，以51单片机为控制核心。相应的管脚在代码的宏定义中有所体现。

用picture控件实现人脸检测画面界面显示和视频流的选择(Achieved with the picture control interface display screen face detection and video streaming options)

说明：  基于STM32的智能垃圾桶，实现的功能有红外传感器检测自动开盖，LED屏显示，温湿度测量，超重报警，异味检测，可燃气体检测(Based on STM32 intelligent trash can, the functions realized include automatic cover opening of infrared sensor detection, LED screen display, temperature and humidity measurement, overweight alarm, odor detection, combustible gas detection)

这是一个在控制面板中增加自己软件所需配置属性的源程序。(This is an increase in the control panel software required for their configuration properties of the source.)

1>实现可以随意浏览任一景点的介绍。（功能一） 2>可以给出任意两个景点的最短距离及其路线。（功能二） 3>可以查看任一景点热度，并可以对对所有景点热度（访问次数）进行排序。（功能三） 4>每个景点相关内容从文件读取，实现对文件操作的练习。 (1> implementations can feel free to browse introduce 任一景 points. (Function a) 2> You can give the shortest distance and route between any two attractions. (Function b) 3> You can view Renyi Jing point heat, and heat can all attractions (visits) to be sorted. (Function c) 4> each spot related content file reading, to achieve the file operations exercises.)

二叉树的简单使用，包括其构建与销毁，以及各种遍历(Simple use of binary trees, including their construction and destruction, and various Traversals)

Matlab中erf(x)函数的表达式是怎样的，erf(x)与标准正态分布函数之间的关系是怎样的，怎样自己编制一个计算标准正态分布函数数值近似值的函数，如何利用matlab自带的erf(x)函数包近似计算标准正态分布函数的值，数值计算值与用erf(x)转化求得的值之间的相对误差是怎样的。(将中文译成英语 Matlab, erf (x) function expression is what, erf (x) the standard normal distribution function and the relationship between what and how to prepare their own calculation of the standard normal distribution function a value function approximation, how to use matlab comes with erf (x) function package approximate standard normal distribution function values??, numerical values ??and with erf (x) between the values ??obtained into the relative error is like. )

开放源码的搜索引擎（Xapian open source search engine）(open source search engine (Xapian open source search engi ne))
