This LDPC software is intended as an introduction to LDPC codes computer based simulation. The pseudo-random irregular low density parity check matrix is based on Radford M. Neal’s programs collection, which can be found in [1]. While Neal’s collection is well documented, in my opinion, C source codes are still overwhelming, especially if you are not knowledgeable in C language. My software is written for MATLAB, which is more readable than C. You may also want to refer to another MATLAB based LDPC source codes in [2], which has different flavor of code-writing style (in fact Arun has error in his log-likelihood decoder).

本程序是一个行计算器（即对表达式求值）。计算器能实现加、减、乘、除、取余（％）和乘方（^）运算；能实现三角函数（正弦函数sin和余弦函数cos），求10为底的对数log，求2为底的对数ln，求e的指数幂exp，其参数也可以是合法的表达式； 计算器并能对表达式的合法性进行测试，错误的能给出表达式错误的信息。 ] 输入文件格式：第一行是一个正整数N，表示有多少行表达式。接下来的N行每一行是 一个表达式。表达式使用由浮点数（只用小数点表示）和运算符表示。 输出格式：每个行输出一个表达式的结果（浮点输出结果使用小数点表示法表示，）

ARP test mode. According to the idea we design the arithmetic for the key part, first the system sends a message to the target machine, and then system wait for the response. Once system receives a message, it starts to analyze the message, according to the message s parameter system judges whether the message satisfies the conditions. Once the message satisfies all the conditions, the system thinks the machine is sniffing, and adds this machine into the list of sniffing machines. On this basis the detection has done well, and at the same time we insert the result into the log database for inquire and analyze later.
