说明：  模糊推理进行灰度图像增强，图片为爱因斯坦的肖像。(Gray fuzzy reasoning for image enhancement, image is a portrait of Einstein.)

This will help you in demonstating and classifying two class variables. This is exclusively meant for signal classification

BLIND IDENTIFICATION OF LINEAR CHANNELS USING THE DATA CONSTELLATION

说明：  自己做的基于MATLAB的dsb编码，已经通过了调试(Do their own code based on MATLAB of dsb has been adopted debugging)

做同步可能用到的几种常见的序列，对做同步的同学有很到帮助。(Synchronization may be used in several common sequence)

Write two e￠ cient MATLAB functions, qrhouse.m and qrgivens.m, that compute the QR decomposition of a matrix using Householder transforma- tions and Givens rotations respectively

采集的加速度信号积分为速度信号和位移信号，好用的程序( Realize the change from acceleration signalto displacement signal or speed signal, Integration program easy to use)

对于初学卡尔曼者有借鉴作用，结合程序可以更好的理解集合卡尔曼理论(For the beginner who has a reference Kalman, combined with a better understanding of the program can be set Kalman theory)

三相交流调压的MATLAB仿真，感觉效果还是挺好的。(MATLAB simulation of three-phase AC voltage, the effect is still feeling quite good.)

File 1: THIS CODE IS USED TO DRAW THE PUMP CURVES AT DIFFERENT PUMP SPEED 1: PUMP CURVE 2: EFFICIENCY CURVE 3: BREAK HORSEPOWER CURVE 4: KW-INPUT CURVE File 2: THIS CODE IS FOR APPLYING THE WAY OF CALCULATING THE EFFICIENCY, POWER AND KW-INPUT FOR VARIABLE SPEED PUMP AT A GIVEN DESIRED HEAD AND DESIRED FLOW AS SHOWN IN THE PAPER TITLED: " how to calculate the pump efficiency and power for variable speed pump" File 3: this code is to correct the use of affinity law by shifting the curve to intersect with the system-curve at the desired flow as shown in the paper titled: "The Correct Method of Calculating Energy Savings to Justify Adjustable-Frequency Drives on Pumps"
