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,)

包含附件中的头文件,就可以在出log时,将log写到文件中,方便调试。
