用全极化的相干矩阵和协方差矩阵，模拟简缩极化的协方差矩阵和Stokes参数(By coherent matrix and covariance matrix fully polarized, polarized analog abbreviated covariance matrix and the Stokes parameters)

学生比赛的时候自行设计的OA办公系统，功能可能不是那么完善(The function of the OA office system designed by the students during the competition may not be so perfect.)

KSVD字典学习算法和MOD字典学习算法，希望对初学者有用(KSVD dictionary learning algorithm and Mod dictionary learning algorithm,hoping to be useful for beginners)

说明：  麻雀虽小,五脏具全!如果想自己做个ftp可以从这个程序做起!(Although sparrows are small, the five viscera are complete! If you want to do your own ftp can start from this program!)

说明：  LS—-dyna碎片撞击模拟，粗糙简单易懂(Ls-dyna fragment impact)

说明：  小波变换去噪、分解与重构，小波变换对信息的去噪以及评价指标(Wavelet transform de-noising, decomposition and reconstruction, wavelet transform de-noising of information and Evaluation Index)

用LabVIEW编写的3D电机模拟程序，可以模拟电机的运动。-Using LabVIEW prepared 3D electrical simulation program, can simulate the motor movement.

S变换时频域滤波是一种二维的时间域—频率域的分析方法，此程序通过对信号进行时频域转换，通过分析干扰信号的时间与频率的分布范围，设计相应的滤波器进行滤波可以有效的去除干扰，又因为S变换的是无损的可逆的因此对信号没有损伤。(S transform time domain filtering is a two-dimensional time domain - frequency domain analysis method. By analyzing the time and frequency domain of the signal, by analyzing the distribution range of the time and frequency of the interference signal, the corresponding filter can be designed to remove the interference effectively, and because the S transform is nondestructive and reversible. There is no damage to the signal.)

这是个运动会记分程序,不知道大家感兴趣不,不过我觉得是我自己写的-Games Points procedures, we do not know is not interested, but I think I wrote it myself
