小波分析Mallat算法经典程序，包含小波谱分析，滤波器，重构算法等。(Mallat algorithm of wavelet analysis of the classical procedures)

FACE DETECTE AND RECOGNITON AND FISHERFACE AND IGENFACE

说明：  卡尔曼滤波器，鲁道夫博士设想的。Kalman(1930-2016)提供了一种有效的机制来估计动态系统的状态，当一个模型可以顺序预测状态和顺序测量也是可用的。在许多实际动力系统的研究中，在不同领域中，这是一种常见的情况。(Matlab implementation of Kalman filter)

说明：  結合webcam 進行人臉辨識並有GUI方便可正確執行(Combined with webcam for face recognition and can facilitate the correct implementation of GUI)

matlab knn图构建以及局部线性重构加权方法(graph construction of KNNG and locally linear reconstruction for weighting the edges of knng)

matlab 与ENVI中数据格式转换，可以很好地实现两者之间的数据格式转换，包括enviwrite,enviread等(matlab with ENVI data format conversion, you can achieve a good conversion between data formats, including enviwrite, enviread etc.)

利用自适应陷波器来消除通信系统中的工频干扰。重点从LMS算法的步长因子、信号与干扰的频率差、参考输入的幅值和相位等几个方面讨论单频陷波器的滤波效果。另外，还以双频为例，讨论了多频级联型陷波器的特性，证实了经过两次滤波后，信号可被真实的恢复出来，且误差收敛趋于稳定。(The use of adaptive notch filter to eliminate the communication system frequency interference. LMS algorithms focus from step factor, the frequency difference signal and interference, refer to the input amplitude and phase of discussions on several aspects of single-frequency notch filter of the filtering effect. In addition, in order to dual-band, for example, discussed the multi-frequency cascade notch filter characteristics, confirmed the filtered twice, the signal can be restored out of true, and the error convergence stable.)
