用双线性变换法设计IIR数字滤波器,程序，用图形显示(Bilinear transformation method of IIR digital filter design, procedures, graphical display)

说明：  最近看到有人提问怎样用FFT实现频谱分析，我认为能够进行到频谱分析的人，对于系统研究的深度基本上已经相当不错了。本人今天做了一个例程，发给大家参考一下。 历程主要内容(signal_analyzer.rar)如下： test1.txt 第一列为时间t，0.001s为步长；第二列为系统的输入信号；第三列为系统的输出信号。 signal_analyzer.m首先将test1.txt 的数据读入workspace，然后进行FFT，分析出两信号的频率，输出对于输入的幅值衰减（db），输出对输入的相位差。(The question was asked recently to see the realization of how to use FFT spectral analysis, I think that spectral analysis can be carried out to those who study the depth of the system basically is already quite good. Today I made a routine, distributed to Members for reference. The main contents of the course (signal_analyzer.rar) are as follows: test1.txt the first time as t, 0.001s for the step the second as the system input signal the third as a system output signal. signal_analyzer.m first test1.txt data read into workspace, and then proceed to FFT, analysis of the two signal frequency, output amplitude for input attenuation (db), the output of the input phase difference.)

各种功率谱估计的源程序,有经典法中的间接法,welch法,现代谱估计中的levinson法,burg法,以及特征分解music法,可以得到仿真结果,自己为论文准备的希望对大家有所帮助(The source of a variety of power spectrum estimation, the indirect method in the classical method, Welch method spectrum estimation in the levinson France, burg France, and feature decomposition music France, you can get the simulation results, the paper ready we hope to help)

利用matlab编程实现RBF神经网络，利用训练模型算法，最后得到较精确的神经网络模型，里面的程序并不需要先前自己进行数据归一化处理(radial basis function)

这是初学真学习SINS的好程序，里面有较详细的注释，方便读懂程序。(This is a good beginner really learn SINS program, which has more detailed notes, easy to read program.)

高斯混合模型的EM搭建过程以及详细说明，利于初学者的学习！(EM Gaussian mixture model building process as well as detailed instructions, which will help beginners to learn!)

　　在目前的人脸图像信息处理领域中，包含有人脸识别、人脸跟踪、姿态估计、表情识别等多个研究方向，然而，所有这些研究方向都涉及到一个人脸标识和定位的问题，即必须知道人脸在图像中的位置以及尺寸——人脸检测。因此，对于一个完整的、自动的人脸信息分析系统来说，人脸检测算法是必不可少的。本文主要是对基于matlab平台的彩色图像皮肤区域分割算法及人脸检测系统的设计做了介绍。(In the face image information processing, including face recognition, face tracking, pose estimation, expression recognition research direction, however, all of these studies are related to the direction of a person the face identify and locate the problem, that is,You must know the position of the face in the image and size- face detection. Therefore, for a complete automatic face information analysis system, the face detection algorithm is essential. This paper introduced the design of the matlab platform based on the area of ​ ​ skin of color image segmentation algorithm and face detection system.)

a comparative study between a PI regulator and fuzzy regulator for a control speed of a Dual Star Induction Machine (DSIM) supplied with two PWM voltage source inverter (VSI) and decoupled by field oriented control (FOC).The simulation results illustrate the robustness and efficiency of the fuzzy regulator to the parametric variations.
