自己在网上看到的一个关于平方根的求值方式，可以参考下(Themselves in line to see a square root to be evaluated on, you can refer to the following)

this code help you to use LBP method.

fisher，用于判别，用于分类，功能很强大，操作很简单(using fisher for determining, for classification)

在MATLAB中，编程确定图像中某一字母位置的源程序，可以使用，图像只有黑白两种颜色(In MATLAB, the program to determine the location of the image source of a letter, you can use, only black and white images)

Calculate the PSNR of two images

粒子群算法，可以自己确定惯性系数的函数式，扩展性良好，可以实现多维(Particle Swarm Algorithm)

BER for QAM include code

Heat equation with variable coeficients using Point Jacobi Method

混合高斯建模方法是目标检测中的一种重要方法( mix gauss detection object )

本文主要利用matlab编程工具对直接序列扩频通信的捕获过程进行仿真。仿真主要基于滑动相关法的有关理论,先讨论扩频仿真中起着重要作用的m序列的生成问题,尔后讨论调制信号的产生,然后在信号的捕获中分步讨论,先对捕获的流程进行简单的仿真,再依次加入噪声和多普勒频移后进行捕获仿真(In this paper, using matlab programming tools for direct sequence spread spectrum communication capture process simulation. Simulation of the sliding correlation method is based on the theory, first discuss the simulation plays an important role in spreading the m sequence generation problem, the modulation signal generation and later discussed, and the signal captured by stepping discussion processes the captured first simple simulation, and then followed by adding noise and Doppler frequency shift after the capture simulation)
