用matlab实现广义最小二乘的数值运算，欢迎大家参考。(Achieve numerical computation of generalized least squares)

在matI ab中模拟c中链表，利用复数运算， 联系具体字符和概率，每次找到最小概率的 两个字符对应的蝙号，依次记录下来，最后 根据奇偶码的不同实现Huffman蝙码。本算法 新颖独特， 易于理解、蝙程。(Simulate in matI ab c in the list, using complex operation, contact the specific character and the probability to find the minimum probability for each of the two characters corresponding to bat number, followed by record, last achieved according to the different parity code Huffman bat code. This algorithm is novel and unique, easy to understand, bat-way.)
