计算机随机模拟日期才用泊松分布，利用指数分布求出时间(Before the date of the computer random simulation with Poisson distribution, calculated using exponential distribution of time)

1. Consider the FIR system described by H(z) = 1/16(-1 + 9z--2 + 16z-3 + 9z--4 - z-6), and plot the pole-zero locations in the z-plane.(1. Consider the FIR system described by H(z) = 1/16(-1+ 9z--2+ 16z-3+ 9z--4- z-6), and plot the pole-zero locations in the z-plane.)

说明：  MATLAB(矩阵实验室的简称)是一种专业的计算机程序，用于工程科学的矩阵数学运 算。但在以后的几年内，它逐渐发展为一种极其灵活的计算体系，用于解决各种重要的技术 问题。MATLAB 程序执行MATLAB 语言，并提供了一个极其广泛的预定义函数库，这样 就使得技术工作变得简单高效。在解决工程技术问题方面，MATLAB 比其它任何计算机语 言（包括FORTAN 和C）都简单高效。本书将介绍MATLAB 语言，并向大家展示如何运 用它去解决经典的技术问题。(MATLAB (short for Matrix Laboratory) is a professional computer program for engineering and scientific matrix math. But in later years, it gradually developed into an extremely flexible computing system for solving important technical problems. MATLAB program implementation of the MATLAB language, and provides an extremely wide range of pre-defined function library, thus making the work easy and efficient technology. In solving engineering problems, MATLAB than any other computer language (including FORTAN and C) are simple and efficient. This book introduces the MATLAB language to show you how to use it to solve the classic technical problems.)

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)

这是一个利用MATLAB的GUI编的长直导线周围电磁场的可视化程序。(This GUI provides a visualization of the electromagnetic field induced by a current flowing in a straight wire. The tool also shows the current induced by a rectangular coil that is placed inside the electromagnetic field. The current is calculated using Ampere s Law and the Biot-Savart Law. This demo was created for educational demonstrations. The user can modify the size and position of the coil, as well as the resistance. The current waveform and magnitude can also be specified.)
