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).

本程序是一個行計算器（即對表達(dá)式求值）。計算器能實現(xiàn)加、減、乘、除、取余（％）和乘方（^）運算；能實現(xiàn)三角函數(shù)（正弦函數(shù)sin和余弦函數(shù)cos），求10為底的對數(shù)log，求2為底的對數(shù)ln，求e的指數(shù)冪exp，其參數(shù)也可以是合法的表達(dá)式； 計算器并能對表達(dá)式的合法性進(jìn)行測試，錯誤的能給出表達(dá)式錯誤的信息。 ] 輸入文件格式：第一行是一個正整數(shù)N，表示有多少行表達(dá)式。接下來的N行每一行是 一個表達(dá)式。表達(dá)式使用由浮點數(shù)（只用小數(shù)點表示）和運算符表示。 輸出格式：每個行輸出一個表達(dá)式的結(jié)果（浮點輸出結(jié)果使用小數(shù)點表示法表示，）

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.
