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"

说明：  潮流计算的matlab编程，分别试了PQ分解法，牛拉法，高斯赛德尔法(The matlab programming of power flow calculation has tried PQ decomposition method, Niula method and Gauss Seidel method respectively.)

this is about space vector modulation

这个是silabs的芯片si1010的发射单音信号的实例，因为涉及保密，所以修改了一部分，测试可用(This is an example of the tone signal transmitter chip si1010 silabs, and because it involves confidential, so modify the part of the test can be used)

该程序是基于MATLAB的磁悬浮系统连续控制的具体程序实现(The program is based on the specific program MATLAB maglev system to achieve continuous control)

具有蒸发率的水循环算法，用来解决无约束优化问题，这是一个比较新的算法(Has the rate of evaporation of the water cycle algorithm, which is used to solve unconstrained optimization problems, this is a relatively new algorithm)

this is the function of the the differential of equation that program the modeling

用matlab编写的在png图像中隐藏并提取rgb图像和二值图像，注意隐藏的图像要小点，源图像png要大些(Png images using matlab hide and extract the rgb image and binary image, pay attention to the hidden image is smaller point source image png)

此源码实现DOA估计中的TCT算法，保证出结果。 (DOA realize that this source is estimated in the TCT algorithm, to guarantee the result.)

This code is an implematation of AIRS1 algorithm. I hope this is helpful.
