该程序是散斑图像中自适应滤波算法处理的matlab程序(The program is adaptive filtering algorithm speckle image processing matlab program)

PWM层叠载波信号，适用于基于IGBT的5电平模块化多电平换能器(PWM stacked carrier signal, suitable for IGBT based 5 level modular multilevel transducer)

说明：  通信信号处理中的七阵元四信号元DOA估计，方法有CAPON、MUSIC、ESPRIT法(Communications signal processing array element seven million four signal DOA estimation, methods have CAPON, MUSIC, ESPRIT method)

基于IP-IQ瞬时功率理论的APF仿真波形图，三相三线，如果需要还可以将三相四线传上来供大家学习交流。(Based on the IP-IQ instantaneous power theory of APF simulation waveform, phase three-wire, if necessary, can be three-phase four-wire pass up for the Learning Exchange.)

小波分析，基于DWT的故障信号特征提取，可以画出条形图，多层分解(Wavelet analysis, DWT-based feature extraction of fault signal can draw bar charts, multi-decomposition)

核Fisher鉴别分析方法（KFDA）。KFDA方法的基本思想是首先将原始训练样本通过一个非线性映射 映射到某一高维(可能是无限维)特征空间F中，然后在F中执行Fisher鉴别分析。(Nuclear Fisher discriminant analysis method (KFDA). The basic idea of KFDA method is the first original training data by a nonlinear mapping  mapped to a high dimensional (possibly infinite dimensional) feature space F, then F in the implementation of the Fisher discriminant analysis.)
