PCA_Face_Recognition

matlab时频分析工具箱，时频分析工具箱包括短时傅立叶变换和二次型时频分析以及各种时频分析的matlab代码(The Time-Frequency Toolbox (TFTB) is a collection of about 100 scripts for GNU Octave and Matlab (R) developed for the analysis of non-stationary signals using time-frequency distributions. It is primary intended for researchers and engineers with some basic knowledge in signal processing.)

说明：  libsvm的参数寻优程序。针对SVR提供full gridsearch方式的参数寻优，主要用于SVM回归预测(libsvm optimization process parameters. Provide full gridsearch for SVR parameter optimization approach, mainly used for SVM regression prediction)

matlab procedures for variables

说明：  6QAM通过带限信道，设码元速率为1000波特，传输信道特性为滚降系数为0.75的滚升余弦频谱的滤波器，试建立测试模型并观察接收信号（等效基带信号）的眼图、星座图和相位转移轨迹图。simulink模型(6QAM through the band-limited channel, located at 1000 baud symbol rate, the transmission channel characteristics for the roll-off factor of 0.75 of spectrum raised cosine filter roll and try to create a test model and observe the received signal (the equivalent baseband signal) of the eye diagram, constellation and phase transfer trajectories. simulink model)

markov2 program in matlab

使用matlab实现的预测程序，希望对预测算法学习 有帮助(forecast program using matlab,can help you study forecast algorithm)

说明：  可以熟悉matlb实现backstepping经典控制算法的例程(Can be familiar with MATLAB to achieve the classic backstepping control algorithm routines)

最短路问题的MATLAB求解，给出图的邻接矩阵输出源点到汇点的最短距离及路线方案，另外根据Floyd算法可得到任意两点的最短距离！(Of MATLAB to solve the shortest path problem is given adjacency matrix output of the source point to the Meeting Point, the shortest distance and route programs, addition, according to Floyd algorithm for the shortest distance between any two points available!)

对信号两端进行镜像延拓,可以用于消除Hilbert变换所带来的端点效应。(to extend both sides of signal)

说明：  利用中心极限定理产生标准正态分布随机数，并进行检验；编制一个界面，产生（0，1）均匀分布随机数，并检验其主要统计量性质。(Central limit theorem using the standard normal distribution random number generation, and tested the preparation of an interface, resulting in (0,1) uniformly distributed random numbers, and verify the nature of the main statistics.)
