计算噪声图像的信噪比，matlab算法程序(Calculate the noise image signal to noise ratio, matlab algorithm program)

应用系统动力学模型，解决在一个封闭的海岛上，对两个群体：1.狐狸(FOXES)；2.啮齿动物（RODENTS）关于生态平衡的问题。详见说明。(With the use of system dynamics model, the program resolves a problem that based on the ecological balance.)

LDPC仿真程序,采用log-BP算法 (LDPC simulation program using the log-BP algorithm)

实现了canny算子的边缘检测，边缘轮廓完整，且抗干扰能力强。(Operator to achieve a canny edge detection, contour integrity, and anti-interference ability.)

Comparing survival curves of two groups using the log rank test

此段代码实现的功能是：用matlab实现了一个神经网络的实例3.(This code implementation is the function: The implementation of a neural network matlab example 3.)

运用最优控制理论，实现对温度的控制，案例为温度控制系统(The use of optimal control theory, to achieve temperature control, case for the temperature control system)

利用单元平均CFAR门限以及单元平均选大CFAR来实现信号的频谱搜索(Using cell average CFAR threshold and average unit chosen CFAR to realize the signal spectrum search )

IEEE802.11(2007) standard for mac and physical layer

好东西，虽然不是很难，但是这样可以节省不少时间，可以把精力投入到难度较大的改进以及应用上了，而不用在大家都会的基本程序上花挺多时间(Good things, though not difficult, but it saves a lot of time can focus into the more difficult to improve as well as the application, and not everyone will be in the basic procedures for the time spent挺多)
