n阶魔方阵，就是把1-n2个连续的正整数填到一个m*n的方阵中，使得每一列的和，每一行的和，以及两个对角线的和都相等。本程序只填奇数阶的魔方阵-n-order magic square, that is, the 1-n2 consecutive filled to a positive integer m* n square in which each column and each row and, as well as two diagonal and are equal. This procedure只填odd order magic squares

C#控制textbox文本框仅能输入数字类型的内容，输入其它类型比如中文、英文字母以及符号时，会被自动删去。

说明：  假设对截断信号 进行采样，设采样间隔为0.5 s。利用离散傅立叶变换和FFT绘制频谱的Matlab实现(Suppose the truncated signal is sampled, and the sampling interval is 0.5 s. Matlab realization of spectrum drawing using discrete Fourier transform and FFT)

桌面弹球是游戏中常见的游戏，从以前的掌上游戏机到如今的手机游戏，都是一个十分经典的游戏。玩家控制一个可以左右移动的挡板去改变运动中小球的移动方向，目的是用小球消除游戏屏幕中的所有障碍物到达下一关，在障碍物被消除的过程中，可能会产生一些能改变挡板或者小球状态的物品，例如：挡板变长、变短，小球威力加强等等。本章主要介绍如何实现一个简单的弹球游戏，让读者了解“动画”的实现原理。(Desktop pinball game is common in game, from the previous game boy to today s mobile games, is a very classic game players control a can move around the damper to change the ball movement direction of the movement, the purpose is to use the ball game screen to eliminate all the obstacles and reach the next level, in the process of obstacle is eliminated, may produce some can change baffle or ball state items, such as: baffle get long become short, ball power to strengthen and so on this chapter mainly introduces how to realize a simple pinball game, let the reader know animation principle )

红外光谱，预处理，PCA，SIMCA,溯源(Traceability of infrared spectrum)

说明：  近场声全息数据和matlab程序，仿真效果好，达到成像的目的(Near - field acoustic holographic data and matlab program, the simulation effect is good, to achieve the purpose of imaging)

主要是实现分类的功能，多分类，很容易理解，更换数据就可以实现不同东西的分类(The main function is to achieve classification)
