该程序专门用于计算，金融证券估值计算股票期权的二项树过程。(The code can be used to plot generated binomial processes of stocks and options.)

用simulink作的MTI高通滤波器的仿真程序，其中输入信号为高斯色噪声，可以对输出作时域和频域分析。(MTI using simulink for high-pass filter of the simulation program, in which the input signal for Gaussian colored noise can be output for the time domain and frequency domain analysis.)

说明：  cootes提出的ASM算法的matlab实现。在cootes用于课堂使用的源代码的基础上改写。改正了原来代码中的一些错误，加入了方便使用的样本训练标注保存环节。供图像分析处理，模式识别，人工智能研究者使用。(the ASM Algorithm Implementation of Matlab. Cootes used in the classroom use of the source code on the basis rewritten. To correct the original source of some mistakes, joined the ease of use of training samples preserved tagging links. For image processing, pattern recognition, artificial intelligence researchers.)

利用Matlab中自带的滤波设计滤波器，非常方便。(Filter design filter comes in Matlab, very convenient.)

matlab实现流行识别，用于多相流的测量(matlab to achieve popular recognition for the measurement of multiphase flow)

说明：  用matlab开放环境实现了对数据的非线性回归，方便好用，直接将数据输入到程序中，便可以实现对数据的非线性回归(Open environment with matlab realize the non-linear regression of data, easy to use, enter data directly into the program, you can achieve non-linear regression of the data)
