纳税风险评估方案及对策,2013西安交通大学数学建模模拟赛matlab代码(Tax risk assessment program and Countermeasures.)

交错网格声波方程正演模拟，PML吸收边界，比较适合刚刚接触的学者。交错网格有限差分地震波场计算，二维的声波正演，利用空间10阶，时间2阶。(The CalCulation of the SeismiC Wave一 fieldwith Staggered-grid Finite difference Sheme)

在这项工作中所使用的方法是基于一个由大卫阿诺德教程。 http://online.redwoods.cc.ca.us/instruct/darnold/diffeq/logistic/logistic.pdf 这将运行该Logistic.m带来了图形用户界面。 1。放弃在列的格式文本文件中的x值 2。放弃在山口格式文本文件中的y值 3。的阴谋初始 按钮将绘制的分布 4。 查找适合 按钮，会找到最适合 5。 重置 将删除的情节（虽然我想打扫所有的领域 -没有时间） 5。地下K，糖尿病在下列公式中的值 Ÿ 等于k/（1+进出口（- G *的（十型录））） 6。上证所给出了squred误差之间的拟合函数与实际数据的总和 7。消委会提供的相关合作关系的实际数据拟合功能和效率(The method used in this work is based on a tutorial by David Arnold. http://online.redwoods.cc.ca.us/instruct/darnold/diffeq/logistic/logistic.pdf RUN The Logistic.m this will bring up the GUI. 1. Give the x values on a text file in column format 2. Give the y values on a text file in col format 3. Plot Initial Button will plot the distribution 4. Find Fit button will find the best fit 5. Reset will remove the plot (Although I wanted to clean all the fields- did not have time) 5. K, G, Dm are the values in the following equation y = K./(1+exp(-G*(x-Dm))) 6. SSE gives the sum of squred error between the fitted function and the actual data 7. CC give the correlation co-efficient between the fitted function and actual data)

国外著名控制专著《extremum seeking control and application》第四章案例matlab源码(matab code for examples of ch4 in a well-known book《extremum seeking control and application》)

对参差动目标检测（MTI）进行仿真研究，画出了其频率响应曲线，可以在源码中改动初始参数来得到想要的仿真(For mixed moving target detection (MTI) simulation study, draw the frequency response curve, the initial parameters can be changed in the source code to get the desired simulation)

说明：  rrt算法在2维和3维环境的规划，均为matlab代码，可用于无人驾驶汽车和移动机器人路径规划(The codes of RRT algorithm in 2 and 3 dimensional environments are matlab codes, which can be used for the path planning of driverless cars and mobile robots)
