一个数=其自身各位数字的立方和，成为水晶花数，此代码解决水晶花问题(A number = number of cubic meters of its own Members, and, as the number of crystal flowers, crystal flowers this code to solve the problem)

PCA主成分分析算法用于人脸识别的例子。此算法是基于矩阵特征值的排序而提取出主要成分的。(PCA principal component analysis algorithm for face recognition example. This algorithm is based on the ranking of the matrix eigenvalue extracted principal components.)

PMSM DRIVES SIMULATION

实现bpsk，qpsk等调制方式的识别用于调制识别的代码，通过提取特征参数，(For modulation recognition code, through the extraction of characteristic parameters, implementation bpsk, qpsk forms of identification, such as modulation)

matlab实现的动画程序：程序运行时，会看到图中的小球沿着曲线周而复始的运动。(matlab s movie:use matlab to draw a figure,which can make the figure to moving like a movie.In this program,you will see a small ball roll along the curve up an down.)

the ESPRIT DOA estimation program

地震合成记录制作的基于matlab的远吗(syntrace )

这是matlab批量读入图片的程序，很好用，里面有详细的说明(This is read into the picture matlab batch process, useful, which is described in detail)

用Simulink中的SimPowersystem完成一个转速、电流双闭环直流调速系统的设计与仿真。采用三相桥式整流，平波电抗器Lp的大小可根据根据仿真调整。给出电机在空载启动，以及在2.5S后加额定负载时转速、电流、电压的变化曲线，并结合调速理论分析这些曲线。(With Simulink in SimPowersystem complete a speed, current double-loop DC speed design and simulation system. Three-phase bridge rectifier, smoothing reactors Lp size can be adjusted according to the simulation. Start the motor load is given, and the speed curve when the rated load after 2.5S, current, voltage, speed and theoretical analysis of these binding curves.)

利用Matlab语言编写，高斯窗实现，进行滤波处理，以及用于后续短时傅里叶变换(It is written in Matlab language, implemented by Gauss window, filtered, and used for short time Fourier transform.)
