设计一个低通数字滤波器，满足如下设计指标： 通带截止频率：0.2pi，通带波动：1dB 阻带截止频率：0.3pi，阻带衰减：15dB 要求：采用切比雪夫Ⅱ型滤波器原型，并分别采用脉冲响应不变变换法和双线性变换法进行设计，比较设计的结果，并进行分析 (Design a low pass digital filters that meet the following design specifications: passband cutoff frequency: 0.2pi, pass-band fluctuations: 1dB stopband cutoff frequency: 0.3pi, stop-band attenuation: 15dB requirements: use of Chebyshev filter prototypes with type Ⅱ and pulse response were the same transformation and bilinear transformation method designed to compare the results of the design and analysis)

说明：  一个非常优秀的人脸检测matlab程序，可用于人脸跟踪、识别的基础，附有测试图片！(A very excellent face detection matlab program can be used to face tracking, recognition based on testing with pictures!)

matlab下模式识别代码 感知机，最小二乘法(Under the pattern recognition code matlab)

Decision region vector For the decision region Number of bins for the data Percentage of incorrectly assigned samples at a nod Unknown command option This function recieves a parameter vector and returns it s components The parameter vector is completely numeric. This is much simpler Percentage of incorrectly assigned samples at a node

本程序设计的是咬尾编码的turbo码，用matlab编写。咬尾turbo码也即不需要拖尾比特，使得前后两个状态相同，译码采用修正的MAP译码算法。此文件为turbo码译码一般的MAP算法，程序中用作与咬尾turbo译码的对照(This program is designed to encode the turbo tail biting code, written with matlab. Tail biting turbo code that is not trailing bits to make the same before and after the two states, the MAP decoding using modified decoding algorithm. This document is a general MAP turbo decoding algorithm, and biting the end of the program for the control turbo decoding)
