说明：  这是一本关于半导体物理学的书籍,从简单的基础入手,希望对相关研究方向的人员有所帮助.(This is a book on semiconductor physics, from the simple basics, hope the staff of the relevant research help.)

An optimized 3d Astar Path planner was uploaded.

使用MATLAB实现运动目标检测，用的是背景差分法(moving detection by matlab)

用此程序中您可以控制鼠标并单击或双击您想要的位置，而不必鼠标！这些项目有利于教学软件。这些程序中还用到C库！(With this program you can control mouse and click or double click anywhere you like without touching mouse ! also upload keyboard_simulation for controlling keyboard without touching it ! These programs is good for teaching softwares. In these programs c library is used ! )

包含多种定位算法，如质心定位、DV-hop、APIT、三角形定位，网格定位等。(Includes various localization algorithms,for instance,centriod,APIT,DV-HOP,Grid Scan.)

这个是收集的一个用matlab编写的车牌定位的程序，很好用的(This is a collection of plates prepared using matlab positioning procedures, good used)

Matlab code necessary

说明：  是基于MATLAB软件编的小程序。该程序是K均值算法，应用于模式识别中(K-mean algorithm)

测绘工程中常用的坐标转换代码，有WGS-xyz坐标系转经纬度、ENU坐标，有北天东坐标系转WGS-xyz、经纬度等(MAPPING commonly used coordinate transformation code, WGS-xyz coordinate system of latitude and longitude turn, ENU coordinate with the northern east coordinates turn WGS-xyz, latitude and longitude)

可以描述光子周期晶格的matlab程序源代码(Photonic lattice can describe the cycle of the source code matlab)
