用模最大值法提取小波脊，该例中又两条小波脊，所以是多脊提取。同时又施加惩罚函数，控制lamda的值，可以得到较为平滑的小波脊。( using maximum modulus extract wavelet ridge, the case has two wavelet ridge, it is a multi-ridge extraction. At the same time to impose the penalty function to control the value of lamda,the extracted ridge can be relatively smooth .)

文件都是文章，全是关于小波神经网络和小波包的，很全。需要的可以下载！(The files are all on wavelet neural network and wavelet packet, very full. Need to be able to download!)

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"

此文件是一测试信道相关性的文件，可以用来对比(This file is the file of a test channel correlation，Can be used to compare。 )

the code of rigid spacecraft model

LS,最小二乘算法，初学者可以很好的应用 (Least-squares algorithm，Applications can be good for beginners)

讲述比较全面是matlab算法，涵盖了许多经典的算法和数学建模的思想。(About matlab algorithm is more comprehensive, covering a number of classic algorithms and mathematical modeling ideas.)

说明：  用于生成带噪声的无人机飞行轨迹，同时通过中值和小波滤波方式进行噪声去除(It is used to generate the flight path of UAV with noise and remove the noise by means of median and wavelet filtering)

此工具箱是英国设菲尔德（Sheffield）大学编写的MATLAB遗传算法工具箱，是使用的最广泛的遗传工具箱之一。在《MATLAB 遗传算法工具箱及应用》作　者：雷英杰 出版社：西安电子科技大学出版社 这本书中重点介绍了此工具箱。( Sheffield genetic matlab toolbox)
