程序模拟的是潜水艇这类大的铁磁性材料穿过海域对电磁场（地磁场）带来的变化以及如何通过物理手段消除这种变化(Program to simulate the submarine through the ferromagnetic material of such a large area of electromagnetic fields (magnetic field), and how the changes brought about this change through physical means to eliminate)

Floyd算法又称为弗洛伊德算法，插点法，是一种用于寻找给定的加权图中顶点间最短路径的算法。 (Floyd algorithm, also known as Floyd algorithm, insertion point method, is used to find a given vertex-weighted graph shortest path algorithm.)

用的新公式编写的Harris角点检测方法，此代码能找到非常多的角点(The new formula used in the preparation of the Harris corner detection method, this code will find a lot of corners)

用于灰色模型的应用，适用于解决简单数学建模的问题。(For the application of grey model, applicable to solve a simple problem of mathematical modeling.)

模糊控制作业，采用模糊控制方法实现，闭环控制，并与传统PID控制比较说明模糊控制的优越性(Operations of fuzzy control, fuzzy control method to achieve closed-loop control, and comparison shows the superiority of fuzzy control and conventional PID control)

matlab对不同风速下的PM海浪谱仿真(Simulation of PM wave spectrum under different wind speeds)

a.阅读的图像img_1.tif，img_2.png的文件夹中，并 他们展示于一体，这两个数字分别。 （参考函数：imread, imshow, figure, subplot） b.在matlab，观察从工作区中的图像信息面板 c.分别使用size, imfinfo,whos等功能获得的图像信息 d.添加标题的图像。 （参考函数：title） Ë 。下面的代码实现的M文件编辑器 f=imread(‘img_1.tif’) imshow(f) set(figure(1), NumberTitle , off , Name , my first image’) 观察结果，并确定的功set() f。保存img_1.tif目录“D： imagetest”。如果该文件夹不 存在，请首先创建这个新的文件夹。 （参考函数：imwrite） (a. Read the images img_1.tif, img_2.png given in the folder, and show them in one and two figures respectively. (referenced function: imread, imshow, figure, subplot) b. In matlab, observe the images information from the workspace Panel c. Use size, imfinfo,whos,etc functions to obtain image information respectively. d. Add title to the images. (referenced function: title) e. Implement the following codes in the M-file Editor f=imread(‘img_1.tif’) imshow(f) set(figure(1), NumberTitle , off , Name , my first image’) observe the result, and determine the function of set() f. Save img_1.tif to the directory “d:imagetest”. If the folder does not exist, please create this new folder first. (referenced function: imwrite))

说明：  模式 识别 matlab程序 很不错的，相信我哦 (Pattern recognition matlab program)

直接4bit替换法的图像伪装技术以及对第四bit考察的matlab代码，其中需要两幅大小一样的图像(Direct 4bit image replacement method camouflage technologies, as well as inspection of the fourth bit of matlab code, one of two required size images)

在保密数据传递等应用中，有时采用将一句话或一段文字或一段音乐隐藏在另一段音乐中，然后利用专门的算法来提取所传的信息(Data transfer in applications such as security, sometimes using the word or a text or a piece of music hidden in another section of music, and then use a special algorithm to extract the information transmission)
