糊涂先生给他的五个朋友写信，他写了五封信，但是当他的朋友收到信后，都告诉他：“你的信寄错了”。那么请你计算一下：出现这种情况的概率有多少？（假设糊涂先生是随机地往信封里装信的），你能不能把所有的情况都列出来呢？-confused to his five friends in a letter he wrote five letters, but when his friend received the letter, had told him : "You sent a letter wrong." Then you do some calculations : this happens the probability is the number? (Assuming confused is randomly installed to envelope the letter), you can put all the cases listed?

科学与工程数值算法（Visual C++版）是一本很好的矩阵类图书。里面有好多源代码可以参考。-science and engineering numerical algorithm (Visual C version) is a matrix of good books. There are a lot of source code for reference.
