说明：  主成分分析算法，有大量数据，初学者可以根据数据看程序，并且可以出现图像(Principal component analysis algorithm, there is a large amount of data, beginners can look at program according to the data, and can appear the image)

雷达脉冲内调制特征的提取技术，用于雷达特征分析与信号分选。这是matlab程序。(Within the radar pulse modulation feature extraction technique for radar signature analysis and signal separation. This is a matlab program.)

求二维点对问题，但是没有实现不知道怎么做？(the distans of some points )

说明：  模拟蚂蚁和食蚁兽的生存规律。在20X20的网格世界里，每个生物每次可向四个方向移动（但不会移除网格边缘），食蚁兽会吃掉在他目标处的蚂蚁(The goal for this programming project is to create a simple 2D predator-prey simulation. In this simulation the prey are ants and the predators are doodlebugs. These critters live in a world composed of a 20x20 grid of cells. Only one critter may occupy a cell at a time. The grid is enclosed, so a critter is not allowed to move off the edges of the world. Time is simulated in time steps. Each critter performs some action every time step.)

矩量法是求解电磁场边界值问题中一种行之有效的数值方法.它所做的工作是将积分方程化为差分方程,或将积分方程中积分化为有限求和,从而建立代数方程组,故它的主要工作量是用计算机求解代数方程组.所以,在矩量法求解代数方程组过程中,矩阵规模的大小涉及到占用内存的多少,在很大程度上影响了计算的速度.如何尽可能的减少矩阵存储量,成为加速矩量法计算的关键.此处介绍了方法(MoM is the solution of electromagnetic field boundary value problem in an effective numerical method. It is the work done by integral equations into differential equations, or integral equations into a finite sum of points, so as to establish algebraic equations Therefore, it is the main workload of the computer to solve algebraic equations. Therefore, in the moment method for solving algebraic equations, the matrix size relates to the amount of memory, to a large extent affected the speed of calculation. how to maximize the reduction of matrix storage has become accelerated MoM calculation of the key. introduce the method here)

VC++实现的GAC水平集， 这样的程序很少见，大部分都是matlab编写的，虽然程序比较简单，但是很有借鉴和参考价值。 有曲线演化的过程(GAC level set VC++ implemented, such programs are rare, and most of them are prepared matlab, although the procedure is relatively simple, but very useful reference and the reference value. Curve evolution process)

CWP:波场中心软件，由SEISMIC UNIX代码改写为matlab版本。(matlab version for seismic unix)

使用吗matlab语言，实现很多模式识别上的经典算法，如PPerceptron_Batch算法等，已通过测试。 (Use the Matlab language, and many classic pattern recognition algorithm, such as PPerceptron_Batch algorithm has been tested.)

练习1：查找内存错误 练习2：阅读书籍高质量ç 编程指南.PDF林锐（林锐）P95，回答问题4。 练习3：阅读代码sizeof.rar。不运行它，它的分析和写入输出。(Practice 1: Finding Memory Bugs Practice 2: Read book 高质量C编程指南.pdf  by Lin, Rui(林锐) P95, answer question 4. Practice 3: Read the code in sizeof.rar. Without running it, analysis it and write the output.)
