分析声音信号的时域和频域特性，并且可以分析声卡输入的声音，自己产生信号(Analysis of the sound signal in time domain and frequency domain characteristics, and can analyze the sound of the sound card input, the generated signal)

可以在matlab上点击，获得点击的坐标值(failed to translate)

it is useful and helpful for my research work

可靠性——有效度最大原则选择维修最佳间隔期(Reliability- the principle of maximum validity choose the best maintenance interval)

Matlab环境下利用Daubechies小波族中的db10小波对散斑退化图像进行了压缩数值仿真研究。研究表明：阈值以及分解层次的选取影响着图像压缩的质量。(Matlab environment using Daubechies wavelet tribal db10 wavelet the withdrawal of speckle image compression for the numerical simulation. Research shows : the threshold level of decomposition is influenced by the quality of image compression.)

This is a project in communication domain. It uses the greedy and RCA algorithm to improve the throughput. It uses window ofdm technique . In transmitter side i used IFFT and in receiver side FFT is used. It uses single user channel .

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"

在MATLAB中，符号计算虽以数值计算的补充身份出现，但涉及符号计算的指令使用、运算符操作、计算结果可视化、程序编制以及在线帮助系统都是十分完整、便捷的。(In MATLAB, the symbolic computation added that though in the numerical identity of the emergence of the instructions involving the use of symbolic computation, operator operation, results visualization, programming and on-line help system are very complete and convenient.)

这是一个简单的数据生成器，可以生成0到1之间的n维数据(This is a simple data generator can generate 0 to 1 between the n-dimensional data)

说明：  这是一个画等值线的图形源程序文件，比较实用(This is a contour drawing graphics source file, more practical)
