Signal-procession

a simple ACP program under matlab

256色转灰度图，用matlab实现一副彩色图像的灰度变换，但必须是bmp格式的图像(256-color to grayscale, using matlab to achieve a color image of the gray-scale transformation, but it must be bmp format images)

The purpose of this program is to calculate the refractive index of a certain material. And you should import some basic optical parameters firstly.

My demonstration program is coded by MATLAB. For the program, some optimization at coding level and algorithm level are proposed to improve the performance of my fingerprint recognition system. These performance enhancements are shown by experiments conducted upon a variety of fingerprint images. Also, the experiments illustrate the key issues of fingerprint recognition that are consistent with what the available literatures say.

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"

Applies different blur filter to each element of a matrix

说明：  把训练数据拷入，load的*.m文件中, 文件中部load的*.m为测试数据 save 存盘的文件为测试数据的bp预测值, 该程序可以扩充n个输入,n个输出,很容易 (Copyed the training data, load the*. m file, the central load of*. m files for test data, save the file to save to disk bp predictive value of test data, the program can be expanded to n inputs, n outputs, it is easy)

多元曲线分辨工具箱，可以处理色谱联用数据，得到纯光谱曲线和色谱图。(Multivariate curve resolution Toolbox, you can handle the chromatography data, the pure spectral curve and chromatogram.)
