face database for face recognition

该文件为FP数据挖掘的matlab程序，文件中包含一个程序文件和一个数据文件，可以方便的进行验证计算。(This is a file for matlab FP data mining program, the file contains a program file and a data file, you can easily verify calculations.)

本文给出Q 矩阵的定义, 在此基础上提出由Q 矩阵构造的LDPC 码新码族(In this paper, the definition of Q matrix Q matrix proposed by the new code of LDPC codes constructed on the basis of race)

说明：  Matlab开发，可以和Access数据库连接，实现成绩查询(Matlab development, Access database connection can achieve results query)

里面是一个自动控制的仿真模型是用matlab的simulink作的(There is a control simulation model is used Matlab Simulink for the)

M序列脉冲响应辨识，系统辨识，采用5级移位寄存器产生M序列作为输入信号，辨识该系统的脉冲响应(M-sequence impulse response identification, system identification, a 5-stage shift register generates M sequence as the input signal, identify the system impulse response)

this gives the basic idea on the placement of capacitor in distribution system.the allocation of capacitor reduces the power losses in the system.

当信噪比低，小信号输入时噪音严重，在整个音域的声音明显变得浑浊不清，不知发的是什么音，严重影响音质。信噪比的大小是用有用信号功率（或电压）和噪声功率（或电压）比值的对数来表示的。(When the signal to noise ratio is low, serious small signal input noise, the sound of the entire range becomes significantly turbid, I do not know what made the sound, seriously affecting the sound quality. Size is the number of the signal to noise ratio by the ratio of desired signal power (or voltage) and the noise power (or voltage) represented.)

说明：  matlab编程，实现灰色预测模型,基于当前已有的数据，用来预测未来一段时间内的发展趋势，对于线性发展趋势拟合情况很好，对于非线性预测差一点。(matlab programming, gray prediction model based on the current available data to predict future trends over time, the linear trends fit in good condition, almost nonlinear prediction.)
