TWO-STAGE-DEA

matlb编写的IIR滤波器程序，按照给定指标采用模拟低通滤波器（巴特沃思低通或者切比雪夫低通）去逼近理想模拟低通滤波器 ，然后通过双线性变换法对模拟滤波器进行数字化，得到数字滤波器 。(IIR filter matlb prepared by the procedure, according to set targets and analog low-pass filter (Butterworth low-pass or low-pass Chebyshev) approximation to the ideal analog low-pass filter, and then through the bilinear transformation method for analog filtering device to digitize, the digital filter.)

Fingerprint Recognition Using Minutiae-Based Features

使用matlab进行积分编程的技巧。介绍了使用int，double命令进行积分的方法。(Integrating the use of matlab programming skills. Describes the use int, double commands integral method.)

BOOST升压电路，输入电压为5v，输出电压为15v,采用无源控制进行系统的闭环控制，调节占空比(BOOST boost circuit the input voltage is 5v, the output voltage is 15v,with passive control for closed loop control system，and change the duty cycle)

说明：  使用svm进行数据的预测，首先进行pca对数据进行主元分析，提取有用信息，结果显示数据拟合效果非常好(SVM is used to predict data. first, PCA is used to analyze the data and extract useful information. the results show that the data fitting effect is very good.)

首先在m脚本文件canshuo.m中输入节点个数和路径权重，在命令窗口中输入canshu，用s=12,e=10的格式输入要求的起止点，再输入main即可得到两点之间的路径和长度。(M script file canshuo.m first enter the node number and the right path lies in the command window enter canshu, with s = 12, e = 10 The format of the input requirements of the start and end points, and then enter the main between two points can be obtained path and length.)
