HHT gcc代码，专门用于希尔伯特黄变换。(HHT gcc code, specifically for the Hilbert-Huang Transform.)

卷积码（2，1，3）编译码matlab程序，简单易懂(Convolutional code (2,1,3) codec matlab)

dbpsk信号的调制解调matlab代码实现的一个例子，调制时差分编码，这样用1bit延迟差分检测的结果，直接就是原码，解调采用1bit差分延迟检测．(DBPSK signal modulation and demodulation matlab code an example of differential modulation encoding, such 1bit delay with the results of differential detection, direct that the original code, demodulation using 1bit delay differential detection.)

无线传感器网络leach协议，在matlab上的改进算法，考虑了能量(Leach protocol of wireless sensor networks, the improved algorithm in matlab, taking into account energy)

使用BP神经网络进行的3维样本分类matlab算法(Using BP neural network of three-dimensional sample classification matlab algorithm)

2D version of Brownian motion. A random walk is similar to markov process, however a markov process has no memory, where a random walk uses an initial state. The next step in the walk does not necessarily depend on your current state but will be referenced from your current state, that is to say the random vector is added to your current state. depending on complexity

the graphs where you can find how the function looks like - sinus

量子阱红外探测器用双周期衍射光栅，光栅图形，光强分布等用matlab程序(Quantum well infrared detectors using double period of the diffraction grating, grating pattern, the light intensity distribution program with matlab)

本文对软件开发中编码作了统一的规定，除非约定发生改变，程序员必须遵守这些约定。(This paper made a unified software development code provisions, unless the agreed changes, the programmer must comply with these conventions.)
