说明：  MathCAD是美国Mathsoft公司推出的一个交互式的数学软件。该软件定位于向广大教师、学生、工程人员提供一个兼备文字处理、数学和图形能力的集成工作环境，使他们能方便地准备教案、完成作业和准备科学分析报告。在输入一个数学公式、方程组、矩阵之后，计算机能直接给出结果，而无须去考虑中间计算过程。在加入软件包自带的Maple插件后能直接支持符号运算。你可以在计算机上输入数学公式、符号和等式等，很容易地算出代数、积分、三角以及很多科技领域中的复杂表达式的值，并可显示数学表格和图形,通过对图形结果的分析，使我们对问题的理解更加形象。 在实际应用中，MathCAD好比是一个功能强大的计算器，它没有很复杂的规则；同时它也可以和Word等字处理软件很好地配合使用，所以也可以把它当作一个出色的全屏幕数学公式编辑器来使用。 Mathcad的用户主要针对具备应用数学知识但并不要求具有较多的计算机知识的用户，如工程研究人员、学生等。 (MathCAD is a Mathsoft Launches interactive mathematical software. The software is targeted to the vast numbers of teachers, students, engineers to provide a mix of word-processing, mathematics and graphics capabilities of the integrated working environment, so that they can make it easier to prepare lesson plans, homework and prepare for scientific analysis. In the importation of a mathematical formula, equations, matrices, the computer can directly give the result without the need to consider the middle of the calculation process. Before joining the Maple software package comes with plug-ins can directly support the operation symbol. You can enter a computer mathematical formula, such as symbols and equations, it is easy to calculate the algebra, Integral, Triangle, and many of the complex field of science and technology in the value of expression, and mathematical tables and graphics show through an analysis of the results of graphics so that our understanding of the issues more imag)

matlab函数scaleif，用于改变度量，详见英文描述( function sim = scaleif(im, newMin, newMax, oldMin, oldMax) Scales an image such that its lowest value attains newMin and it highest value attains newMax. OldMin and oldMax are not necessary but are useful when you don t want to use the true min or max value.)

编写查找程序search，功能如下：给定任意有序数列，然后输入任意一数，用折半查找法找出该数在数列中的位置，若数列中有此数，则返回该数在数列中所在的位置，若数列中无此数，则返回-1 把给定值y插入到有序数组a（由大到小）中，插入后，数组中的数仍然有序 用递推法求解：一串字符以问号“？”结尾，顺序读入后反向输出，且统计其中字符的个数(prepare you search procedures, functions as follows : Given a series of arbitrary order, then enter an arbitrary number, using binary search method to find the few series in the position, if the series is this, Return of the few series in the location, if the series has been no such number,-1 is returned will be distributed to value y orderly array inserted into a (decreasing), insert after The array is an orderly with a few recursive method : a bunch of characters with a question mark "?" The end of the order after reading the reverse output and statistics on the number of characters)

用MATLAB首先显示彩色图像，然后显示灰度化后的图像，再绘制直方图，直方图均衡化(MATLAB show color image first, and then according to gray image, to draw the histogram, the histogram equalization)

遗传算法的电机优化程序，个人专门编写的，对于初学者来说，可以借鉴(function youhua1() 遗传算法 n-- 种群规模 ger-- 迭代次数 pc--- 交叉概率 pm-- 变异概率 v-- 初始种群（规模为n） f-- 目标函数值 fit-- 适应度向量 vx-- 最优适应度值向量 vmfit-- 平均适应度值向量 clear all close all clc 清屏 tic 计时器开始计时 n=20 ger=100 pc=0.9 pm=0.1 初始化参数 生成初始种群 v=init_population(n,44) 得到初始种群，22串长，生成20*22的0-1矩阵 [N,L]=size(v) 得到初始规模行，列 disp(sprintf( Number of generations: d ,ger)) disp(sprintf( Population size: d ,N)) disp(sprintf( Crossover probability: .3f ,pc)) disp(sprintf( Mutation probability: .3f ,pm)) sprintf可以控制输出格式 待优化问题)

该源码来自教程＜先进的pid控制及matlab仿真（第一版）＞，对初学者非常有帮助.(The source code from the tutorial <advanced pid control and matlab simulation (first edition)>, very helpful for beginners.)

这个是一个很详细的介绍了声学测量的内容和方法，是西工大的教学材料，希望对学习心理声学的同学有帮助。(This is a very detailed description of the acoustic measurement of the Neirong and the method is NPU teaching materials, Xi Wang students learning psychoacoustic help.)
