扩频通信，从电磁波利用来看，与一般现有的常规通信方式完全不同。扩频通信利用伪随机编码把信息数据（窄带信号）的频谱进行扩展，形成宽带的低功率谱密度信号发射，使用不同的伪随机序列编码，不同通信用户可在同一频段、同一时间工作，互不影响或干扰极小地进行通信。(Spectrum, from the electromagnetic waves used term, and the general existing conventional means of communication is entirely different. Spread spectrum communication using pseudo-random code to the information data (narrowband signal) to extend the spectrum, the formation of low-power spectral density broadband signal transmission, using different pseudo-random sequence of coding, different communication users at the same frequency band, at the same time work, mutual does not affect or interfere with a very small way to communicate.)

本段代码主要是为了实现讲多光谱图像进行光谱分离然后再合并成一种可以在matlab中显示的格式.tif的图像，同时保证了原始的图像信息不丢失(This code is mainly to achieve multispectral images speak for spectral separation and then combined into a format that can be displayed in matlab. Tif image, while maintaining the original image information is not lost)

应用LMS算法，用Matlab编程实现系统识别.(Application of LMS algorithm, using Matlab programming system identification.)

Segmentation by growing a region from seed point using intensity mean measure.Simple but effective example of "Region Growing" from a single seed point.

Matlab常用命令文档,三部分,包括各种例子,充分让你了解各个命令的使用方法.(Matlab commands commonly used documents, in three parts, including a variety of examples, and fully understand the command you use.)

说明：  简单眼图，适用于初学者，仅仅是简单的代码，高手请绕道(Simple eye)

这是一个非常重要的而又简单的程序，是书上常用和数学建模的好帮手( very good)

说明：  如果厚度为5mm的物质对500nm光的折射率为1.4，对600nm光的折射率为1.5，画出500nm与600nm光同时照射时候观察屏上的强度分布 对牛顿环进行模拟(Newton ring analog if a thickness of 5mm substances on the refractive index of light of 500 nm is 1.4, the 600nm light refractive index of 1.5, draw 500nm and 600nm light irradiation when the intensity distribution on the viewing screen )
