现行调频生成函数，直接运行即可，运行后可以生成LFM信号，并给出幅度频率图(FM existing generating function, can be directly run, run after the LFM signal can be generated, and gives the frequency range of Figure)

一个对于光孤子的编程。程序比较简单，但是结果比较实际，推荐。(For the programming of a soliton. Procedure is simple, but the results more practical recommendation.)

Algorithm for Generating Random Number with Multi-dimensional Discrete Distribution

趋势面分析是拟合数学曲面的一种统计方法。通常要找到一个合适的曲面精确表达实际问题往往比较困难，但却可以利用多项式函数来近似逼近它。(trend surface analysis is fitting surfaces of a mathematical statistical methods. Usually to find a suitable surface accurately reflect the actual problems are often more difficult, but polynomial function can be used to approximating it.)

MATLAB 从入门到精通这本书里的源代码和所有附图(MATLAB from approaches to master this book of source code and all the appended drawings)

write a binary data to the disk

也是利用最小二乘法对椭圆进行数据拟合，不过考虑到图像大小问题，这里只选取100个边缘点，点的个数也可以自行设置。(Ellipse is the least square method of data fitting, but taking into account the size of the image, here select only edge points 100, the number of points you can set your own.)

设计一M阶自适应回波抵消器，已u(n)作为系统输入，d(n)作为系统期望响应，其中d(n)中混有u(n)的回声，信号以8kHz采样，现要求回波抵消器可以消除16ms之内的回声(The design of a M-order adaptive echo cancellation, and have u (n) as the system input, d (n) as a system to respond to the expectations, in which d (n) in a mixture of u (n) of the echo signal to 8kHz sampling, are requirements 16ms echo cancellation device can be eliminated within the echo)

基于肤色的人脸检测MATLAB源代码皮肤检测的最终目标是构建一个决策规则，并以此将图像中的像素划分为肤色和非肤色两类，一般通过引入一个衡量像素点颜色与“标准肤色”的距离而实现的，该距离是由相应肤色建模的方法决定的(Face detection based on skin color skin detection MATLAB source code for the ultimate goal is to build a decision-making rules, and use of the image pixels into skin and non skin types, usually by introducing a measure of the pixel color with the " standard colors" achieved the distance, the distance of the corresponding color from the decision modeling approach)

这是一本很少见的中文matlab帮助手册，特别对于点运算等入门级知识进行了详解，大家共享吧！(This is a very rare Chinese matlab help manual, particularly for entry-level point of computing, such as the detailed knowledge, share it!)
