求解圆周率pai的经典程序

关于求矩阵秩的程序，用高斯―约当消元法实现-On the procedure for matrix rank, using Gauss- Jordan elimination method to achieve

I have developed a serial of resampling methods for particle filtering in Matlab as attached below in separate .m files that you may have interest and that you may have better implementation than me, or if you have any question, your feedback will be appreciated.  These resampling methods together with their pseudo-codes

详细说明：2DPCA用于人脸、步态等图像识别，可先按照行列比例将不规整图像归一化处理，然后进行训练，并且识别，全部中文注释和提示，便于学习和参考。-2DPCA humanface, gait, such as image recognition, in accordance with the ranks of theratio can not structured to deal with the normalized image, and then training,and recognition, all Chinese notes and tips for learning and reference.

我提出了一个伪谱的显式方案，可以模拟低频电磁 （EM） 传播在地球。该方案解决了线性周期抛物型方程， 具有内机精度精密，两个时间和空间。

大数阶乘，能计算超大数的阶乘，算法简单易懂，采用数组存储计算结果！本算法也可以改进采用链表存储结果！-majority factorial, which calculates the number of super factorial, the algorithm is simple to understand and use storage arrays results! The algorithm also can be improved using Chain store results!

一个用C语言写的FFT算法，经测试，效果很好-More use of a FFT algorithm C

应用背景你玩儿过扫雷游戏吧？Windows操作系统中带了这个小游戏，那个系统叫什么来着？在游戏中要想过关，就必须要在一个 NxM 的区域上找出所有的地雷。游戏过程中，计算机会在地图上显示一些数字从而帮助你确定哪里有地雷。关键技术Have you ever played the game? Windows operating system with this little game, the system called what? In the game to pass, it is necessary to find out all the mines in a NxM area. In the process of the game, the computer will show some numbers on the map to help you identify where you are.
