一是利用计算机对正整数进行素因子分解认识素数，通过运用筛法与试除法寻找一定范围内的素数，体会到筛法比试除法有效但无法找出所有素数；二是通过若干特殊形式的素数的研究，寻找素数生成公式，发现一些结论；三是借助于非线性拟合技术，观察素数分布规律，利用其研究有关数论问题。(The first computer was used to prime factor decomposition of positive integers understanding of prime numbers, through the use of screening method and trial division to find prime numbers within a certain range, the division experienced a test of an effective screening method but can not identify all the prime numbers second is through a number of special form of prime numbers research, looking for prime number generation formula, found that some of the conclusions third, by means of non-linear fitting technique to observe the distribution of prime numbers, using their research on number theory problems.)

用LLE算法来实现高维空间中流行的降维,从而在低位空间中有效表示该流行(to decrease the dimension of manifold embedded in high dimension space )

ekf滤波器程序，用于导航方面的。用MATLAB写的。还行(ekf filter program, used for navigation. Written using MATLAB. Okay)

Beamforming _M _QAM

给出具体的电源规划问题解决方案，采用matlab程序语言进行编写。(The specific solution of power planning problem is given, and the program language of MATLAB is used to compile it.)

说明：  可以通过CST得到透射系数计算超材料的不对称传输系数(The transmission coefficient can be obtained by CST to calculate the asymmetric transmission coefficient of metamaterials.)

说明：  几种传统的图像插值放大方法：最近邻插值法，双线性插值法，双三次插值法(Several traditional interpolation to enlarge the image : nearest neighbor interpolation, bilinear interpolation, bicubic interpolation.)

cdma系统matlab仿真，在两个用户的背景下采用了直接扩频码实现扩频解扩，bpsk调制解调，程序已经运行过，没有问题！(cdma system matlab simulation, in the context of two users using a direct spread spectrum spreading codes realize despreading, bpsk modem, the program has been run before, no problem!)

实现图像的基本操作，可对图像进行一些简单的操作，比如图像增强，图像恢复等等(To achieve the basic operation of the image may be an image of some simple operations, such as image enhancement, image restoration, etc.)
