AHP层次分析算法的MATLAB源文件。包括三个部分，一个主函数脚本文件，输入判断矩阵，两个函数文件分别实现求最大特征根、特征向量及一致性检验。(AHP AHP algorithm MATLAB source file. Consists of three parts, a main function of the script file, enter judgment matrix, two function files are seeking to achieve maximum eigenvalue eigenvector and consistency checking.)

霍夫曼编码的具体方法：先按出现的概率大小排队，把两个最小的概率相加，作为新的概率 和剩余的概率重新排队，再把最小的两个概率相加，再重新排队，直到最后变成1。每次相 加时都将“0”和“1”赋与相加的两个概率，读出时由该符号开始一直走到最后的“1”， 将路线上所遇到的“0”和“1”按最低位到最高位的顺序排好，就是该符号的霍夫曼编码。(Specific methods Huffman coding: the probability of emergence of the size press line, the two smallest sum probability, as a new probability and the probability of re-queue the remaining, then the minimum of two probabilities are added, and then re-queue, until finally become one. Each time the sum will be 0 and 1 Fu added two probabilities, when read by the symbol has come to begin the final 1 , the route will encounter a 0 and 1 at the lowest to the highest bit of the right order, that is the symbol of the Huffman coding.)
