此文件是求《矩阵特征值问题条件数的估计》的一个matlab文件(This file is to strive for " the condition number of matrix eigenvalue problem of the estimate" a matlab file)

费舍尔判别法的人脸识别应用程序例子，希望有所帮助(Fisher Discriminant Method for Face Recognition application example for the help)

本程序为一段信号相关分析，定义了一个相关函数，用的时候直接调用即可。由于上传匆忙，有地方未修改，下载者请将pCorr这个程序段中Rxy(i)=Rxy(i)/i这段删掉，否则会出错(This program is a signal correlation analysis, the definition of a correlation function, when used in direct calls to)

用于解决单相并网中的锁相环问题，并实现相应的仿真验证探究。(To solve the problem of single phase grid connected in phase locked loop)

基于混沌掩盖技术，讲超混沌反同步系统应用到密保通信中(Based on chaotic masking technology, ultra-speaking anti-synchronization of chaotic systems is applied to the secret security communication)

基于L阵的二维信号稀疏分解的DOA估计 应用稀疏分解方法进行二维DOA估计(Estimation sparse decomposition method based on two-dimensional signal-dimensional DOA estimation of sparse matrix decomposition L DOA)

matlab解耦合非线性薛定谔方程组，考虑自相位调制、交叉相位调制与四波混频(Matlab solves the coupled nonlinear Schrodinger equations, considering self phase modulation, cross phase modulation and four wave mixing.)

音频信号降采样程序 支持48k->8k 24k->8k 8k->1k 的降采样.实现方法,先做低通滤波,再做采样点抽取.低通滤波起使用67点FIR,系数由matlab使用窗函数法生成 (Audio signal down-sampling procedures to support the 48k-)
