基于MATLAB-GUI图形界面的数字图像处理软件 (MATLAB-GUI graphical user interface based on digital image processing software of the system )

说明：  matlab最常用命令 1.有关命令行环境的一些操作:  (1) clc 擦去一页命令窗口,光标回屏幕左上角  (2) clear 从工作空间清除所有变量  (3) clf 清除图形窗口内容  (4) who 列出当前工作空间中的变量  (5) whos 列出当前工作空间中的变量及信息  或用工具栏上的 Workspace 浏览器 (matlab command most commonly used 1. on the command-line environment, a number of operations:  (1) clc remove a command window, the cursor back to the top left corner of the screen  (2) clear working space from the removal of all variables  (3) clf clear the graphics window content  (4) who are listed in the current working space of variable  (5) whos lists the current working space of variables and information  or Workspace toolbar browser)

It provides complete, clear, and detailed explanations of advanced electri- cal engineering concepts illustrated with numerous practical examples.

一个报童从报刊发行中心订报后零售，每卖一份报纸可赚钱a元；若报纸卖不出去，则退回发行处，每退一份要赔钱b元。每天报童卖出的份数是随机的，但报童可以根据以往卖报情况统计得到每天卖k份报纸的概率密度p(k)。 （1） 求报童每天期望收益达到最大（或损失达到最小）的定报量z。 （2） 改变参数a/b的值，观察订报量的最优值变化，画出变化曲线。 试画出仿真流程图，进行程序实现，并对仿真结果进行分析。 (A newsboy subscribe from the press after the retail distribution centers, each sale of a newspaper can make money a million if newspapers can not be sold, then returned to Issue Department, each retire to a loss of a b element. Newsboy sold shares in a day is random, but the newsboy can sell based on past statistics reported to be selling daily newspaper k the probability density p (k). (1) seeking newsboy expected profit per day to maximize (or minimize loss) reported that the volume of fixed-z. (2) change the parameters a/b values, subscribe to observe changes in the volume of the optimal value, draw curve. Simulation test to draw a flow chart for program realization, and simulation results for analysis.)

写入for3d程序需要的in文件，此例是以具体应用中的具体问题而写。(also a programme that product the infile of for3d programme.)

matlab中文help 比较小，但对初学者比较有用。(matlab Chinese help relatively small, but more useful for beginners.)

说明：  matlab实验 用给定的多项式，y=x3-6x2+5x-3，产生一组数据(xi,yi，i=1,2,…,n),再在yi上添加随机干扰(可用rand产生(0,1)均匀分布随机数,或用rands产生N(0,1)分布随机数)，然后用xi和添加了随机干扰的yi作的3次多项式拟合，与原系数比较。 如果作2或4次多项式拟合，结果如何？ (matlab experiment with a given polynomial, y = x3-6x2+5 x-3, generated a set of data (xi, yi, i = 1,2, ..., n), then add random noise in yi (available rand generation (0,1) uniformly distributed random number, or rands generated N (0,1) random numbers), then xi and yi to add a random disturbance polynomial fitting for the three times, compared with the original coefficient . If 2 or 4 times for polynomial fitting, the result?)
