计算地震波的震中距和走时的的子程序，非常好用的子程序(Subroutine to calculate seismic epicentral distance and travel time, and very easy to use subroutines)

3d 平面波 科技进行仿真平面波的传播 应用在matlab 当中，直观简洁(3d plane wave)

说明：  这是一个计算图像中的欧拉数的程序.先将图像二值化,然后再求反计算欧拉数(This is a calculated image of the Euler number of procedures. First two binary images, and then calculated for anti-Euler number)

利用迭代法实现图像阈值分割，简单好用，自带matlab图像直接运行(terative method to achieve image segmentation, easy to use, comes directly run matlab image)

This powerful code helps you determine the static voltage stability of a power system. The code is really useful for power engineers.Also it can determine the optimal location of a DG to improve the voltage stability limit of power system.

模拟退火工具箱和相关的源代码，非常有用，希望大家共享学习(Simulated annealing toolbox and related source code )

改进后的直接转矩控制系统，绝对能用。matlan/simulink7.4(Improved direct torque control system, the absolute use. matlan/simulink7.4)

直线一级倒立摆LQR 控制MATLAB 计算程序,绝对正确.(Linear inverted pendulum LQR control a MATLAB program, absolutely correct.)

本文件为深圳杯数学建模大赛D组题目的全部相关程序，没有题目 只有解答过程和程序~已经把数学问题精炼出来了(This document is all related procedures for group D questions of shenzhen cup mathematical modeling contest. There are no questions, only the solving process and procedures. The mathematical problems have been refined.)
