利用2DPCA和2DLDA在ORL人脸数据库上做的人脸识别实验，注解详细，适合初学者使用，对理解PCA与LDA有很大的作用。(2DPCA and 2DLDA use in ORL face database for face recognition experiments do, comment in detail, suitable for beginners, on the understanding of PCA and LDA are very useful.)

说明：  连续信号的相关于褶积。本程序在matlab上已经测试，可以直接调用。(Continuous signal related to the convolution. This procedure has been tested in matlab can be called directly.)

说明：  特别好的matlab源程序的学习案例，方便大家学习，欢迎下载！！(Particularly good case study matlab source, to facilitate learning, welcome to download! !)

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(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, decoding, MAP decoding algorithm using modified)

The function takes three input arguments (function and two initial guesses belonging to the interval). After iterations, it returns the root of the function. The fourth input argument is to change the stopping criteria of the loop.
