matlab编程的循环统计量的仿真程序，运行了效果还行，可能有些地方不太好，敬请指正(matlab programming cycle statistics of the simulation program, run the results were OK, there may be some places not very good, please correct me)

本软件研究了地基的计算方法，并通过matlab对建筑工地上的地基扰度进行了数值计算，很好的解决了以前性能差的问题(This software to study the method of calculating the foundation, and through matlab on the construction site disturbance foundation degree has been calculated, a very good solution to the previous poor performance)

matlab算法大全，包含了许多常用算法的matlab源代码，是数学建模等的必备工具(matlab algorithm Daquan, contains many commonly used algorithm matlab source code, is an indispensable tool for mathematical modeling)

三类目标的散射点模型，分别建立模型，并且画图，三个文件代表三类对象(Three types of target scattering point model)

说明：  用matlab实现的FFT例程，对于FFT理解入门及实现是很好的参考(Matlab implementation of the FFT routines used for the FFT is a very good understanding of induction and the reference implementation)

图片印刷字符的识别（可识别多种字体） 将Matlab工作空间路径设置为本文件夹 在Matlab命令窗口内输入： numCongnition( able1/01.jpg ) 通过改图片来对不同的图进行处理，其中able1,able2,able3三个文件夹分别对应三种字体 命令窗口输出要识别的字符，并且自动弹出中间处理过程窗口 也可以运行： num = pretreat( able1/01.jpg ) imshow(num) 直接得到预处理后的图片 再键入： getNumber(num) 得到字符输出 (Set the Matlab workspace path to this folder In the Matlab command window input: NumCongnition ( able1/01. JPG) Through change pictures to deal with different figure, including able1, able2, able3 three folders corresponding to three kinds of fonts Command window output to identify characters, and automatically process among popup Windows Can run: Num = pretreat ( able1/01. JPG) Imshow (num) Directly after preprocessing of images Type: GetNumber (num) Get the output character)
