用于地震学中的正演波形计算和波形拟合，也可用于地震勘探中，用途广泛(a software that can forward the waveform )

说明：  PCA人脸识别 This package implements basic Principal Component Analysis in Matlab and tests is with grayscale portion of the FERET database. Images are not preprocessed and it is up to the user to preprocess the images as wanted, not changing the filenames(PCA Face Recognition This package implements basic Principal Component Analysis in Matlab andtests is with grayscale portion of the FERET database.

说明：  基本的Qpsk调制和解调方式，采用的是A方式，并且画出误码率和信噪比的比例图(QPSK simulation)

本文讲述锁相环的工作原理，锁相环路实际上是一个相差自动调节系统。(This article describes the working principle of PLL, PLL is actually a difference between the automatic adjustment system.)

用matlab编写的信号发生系统，能够实现信号的发生及叠加。(System able to signal the occurrence of superimposed signals using matlab.)

This file is the programs of (chapter 1) of book (Modeling the Wireless Propagation Channel a Simulation Approach with MATLAB) which is related to introduction to wireless propagation. It helps you to simulate wireless channel and wireless statistical models with PDF and CDF.

matlab在系统辨识中的应用此处为递推的极大似然法应用的源代码及运行后结果（包括图像）(Matlab system identification in the application of recursive here Maximum Likelihood of the application's source code and running after the results (including images))

a new version of implemented FCM on matlab

（1） 本系统用到四种神经网络对漏电嫌疑系数进行预测，分别是BP神经网络、RBF神经网络、GRNN神经网络、Elman神经网络，通过对神经网络结构参数的设置和调试，可以得到很好的预测效果，实际值和预测值之间的误差能达到5 以内。 （2） 本系统使用matlab做GUI界面，在界面上就可以分别对这四种神经网络的结构参数进行设置，从而可以调整神经网络的结构，达到较好的预测精度。 ((1) The system used four neural network to predict the suspected leakage coefficient, respectively, the BP neural network, RBF neural network, GRNN neural network, Elman neural network, the neural network structure parameter setting and commissioning, can get very good prediction, between the actual and predicted values ​ ​ of error of less than 5 . (2) the use matlab to do the GUI interface, the interface can each of these four neural network structure parameters set, the structure of the neural network, which can be adjusted to achieve better prediction accuracy.)
