matlab源程序，计算系统的相关系数，用于系统各因素的影响度分析。(matlab source code, computing the correlation coefficient for the system factors analysis.)

这个matlab程序可以同时对图像做高斯滤波和中值滤波处理。(The matlab program can do Gaussian image filtering and median filtering.)

Sunspot activity is cyclical, reaching a maximum about every 11 years. Let s confirm that. Here is a plot of a quantity called the Zurich sunspot relative number, which measures both number and size of sunspots. Astronomers have tabulated this number for almost 300 years.

用了三帧差分法、背景差分法来辨别图片中的运动物体，包含了报告和算法说明(Spent three difference method, background subtraction method to identify pictures of moving objects, including a description of the report and algorithms)

在偏微分方程的数值求解中，有一类很重要的问题就是求解有奇异点的泊松方程，此程序是用C写的并行程序，能极大的提高泊松方程的求解(In the numerical solution of partial differential equations, there is a class of very important issues that have a singular point of solving the Poisson equation, this program is written in C parallel programs, can greatly improve the solution of the Poisson equation)

说明：  D=1m d=2mm 当在一个缝的位置放置一个折射率n=1.4, 厚度为5mm的物质，不考虑损耗，画出此时的双缝干涉的图样 (D = 1m d = 2 mm when placed in the position of a seam of a refractive index n = 1.4 and a thickness of 5mm for the substance, and does not consider the loss, to draw the double-slit interference pattern)

采用CIC（级联积分梳状）滤波器实现降采样的功能，并分析了级联级数、差分延时数对CIC滤波器幅频响应的影响；采用Verilog语言实现了CIC滤波及降采样的功能；(Using CIC (Cascaded Integrator Comb) filter down-sampling function, and analyzes cascaded stages, affecting the number of differential delay CIC filter amplitude-frequency response using Verilog language of the CIC filter and down sampling Features )

平滑LMS自适应滤波器，实现信号的自适应滤波作用。(Smooth LMS adaptive filter, adaptive filtering effect the signals.)

本书的目的是让读者熟练掌握MATLAB的知识并用来求解工程问题。解决这类问题一般需要编写相对较短、使用次数较少的程序。因此，本书将着重介绍在MATLAB中如何有效地开发简洁易读的程序，同时使之具有易于调试和执行速度快的特点。(The purpose of this book is to allow readers to master knowledge of MATLAB and used to solve engineering problems. To solve such problems usually need to write a relatively short period, the use of fewer procedures. Therefore, this book will focus on how to effectively develop in MATLAB concise, easy-to-read program, so that it has easy debugging and execution speed.)
