PI regulation as an example of one of most polupalar methods of usage classical control system methods.

根据的给出降水量，返回干旱历时、烈度、时间.以均值、0.8的均值、0.6的均值为阈值。(according to the given precipitation ,calculate the last time,intensity and the start time of arid.)

％File: c9_estimatepi.m ％有5个pi的估计，每一个都是基于500次重复随机试验，所得的pi的五个估计值用以下向量表示 ％pi的估计值=[3.0960 3.0720 2.9920 3.1600 3.0480] ％如果对5个结果进平均，则pi的估计值=3.0736,这样的结果等价于2500次的试验结果。( File: c9_estimatepi.m have 5 pi estimates are based on a randomized trial to repeat 500 times the income of the five estimated value of pi with the following vector, said the estimated value of pi = [3.0960 3.0720 2.9920 3.1600 3.0480] if the results into an average of 5, then the estimated value of pi = 3.0736, so the result is equivalent to 2500 times the test results.)

BPSK系统的误码率仿真的详细的matlab程序～～～～～～～(BPSK BER simulation of the detailed matlab program ~~~~~~~)

本文件是我们小组参加2013电工杯的数学建模比赛的文件，荣获全国2等奖！我们做的是电力系统分析的题目，内有基于matlab建立的三次平滑统计方法，以及神经网络智能算法，还有就是基于simulink的电力系统仿真程序！内附有程序说明文件。你一定能看懂的，不懂的可以留言给我！(This document is our electrician Cup 2013 team participated in the mathematical modeling of the game files, won the two prize! What we do is the subject of power system analysis, there are statistical methods based on cubic smoothing matlab established and intelligent neural network algorithm, there is a power system based on simulink simulation program! Enclosing a program documentation. You must be able to read and understand can leave a message to me!)

有关可变码长的LDPC编码电路的设计与实现和一些相关的英文资料以及文献(LDPC)

通过卡尔曼滤波并采用开环控制方式实现惯性导航和GPS的数据融合(Through the Kalman filter and use the open-loop control method to achieve inertial navigation and GPS, data fusion)

说明：  很不错的LDPC译码的matlab程序，觉得有用大家分享一下(LDPC decoder)

线性判别法（LDA），用来降维的，找了好久了，很好用(Linear discriminant method (LDA), used to dimensional reduction, for a long time, very good )

说明：  file is being described
