This method is used for tracking wavelet/optical flow-based detection for automatic target recognition in the following paper: Dessauer, M. and Dua S. “Wavelet-based optical flow object detection, motion estimation, and tracking on moving vehicles”

MATLAB程序实现日历的一个小程序。希望感兴趣的朋友可以看下。(MATLAB program to achieve a small calendar program. Hope interested friends can look.)

matlab判别分析，基本思想是将高维的模式样本投影到最佳鉴别矢量空间，以达到抽取分类信息和压缩特征空间维数的效果，投影后保证模式样本在新的子空间有最大的类间距离和最小的类内距离，即模式在该空间中有最佳的可分离性。(matlab discriminant analysis, the basic idea is to sample the high-dimensional pattern projected onto the optimal discriminant vector space, in order to achieve the classification of information extraction and compression feature space dimension effect, the projected sample assurance model in the new subspace has the largest class room the intra-class distance and the minimum distance, i.e., have the best separability pattern in the space.)

导入振动信号（2信道）分析时域、频域波形的MATLAB-GUI界面(Import vibration signals (2-channel) analysis in time domain and frequency domain by MATLAB-GUI interface)

RSA is one of the first practical public-key cryptosystems and is widely used for secure data transmission. In such a cryptosystem, the encryption key is public and differs the decryption key which is kept secret. In RSA,
