用两种向量化和一种循环的思路计算水仙花数，并给出所需时间比较 水仙花数是指一个三位数,其各个数的立方和等于该数(Quantified in two and a loop to the idea of calculating the number of daffodils and narcissus are given the time required for comparison is a three-digit number, the individual cubes, and equal to the number of)

说明：  通过时域转换为频域，在频域中截取低频部分，去掉高频部分将结果再转换到时域以实现低通滤波的功能。(Through the time domain is converted to frequency domain, in the frequency domain low-frequency part of the interception, to remove high-frequency part of the results and then switch to the time domain in order to achieve low-pass filter function.)

说明：  bp神经网络的预测，烧结式氧化铝的返料成分的在线预测(bp neural network prediction, the online prediction of the return material composition of the sintered alumina)

人脸识别的pca算法,可以运行，是源代码(Face recognition pca algorithm, you can run source code)

matpower，电力系统的潮流计算程序，包涵所有的IEEE节点数据(MATPOWER power flow calculation procedures, includes all IEEE nodes data)

说明：  MATLAB图像处理源程序6： 程序代码说明 P0610：神经网络的实例 (MATLAB image processing source code 6: Procedure Code Description P0610: examples of neural network)

二维的TM波打到一个方形的金属柱上，边界条件为PML(TM wave hit a two-dimensional square metal column, PML boundary conditions)

Program will calculate the region of interest with free hand sketch and the selected will be shown

this is to code stbc simulation

its a matlab discription of varius digitl filers both in special and frequency domain. very useful for beginners.
