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).

贪吃蛇*要点分析: *1)数据结构:matrix[][]用来存储地图上面的信息,如果什么也没有设置为false, * 如果有食物或蛇,设置为true;nodeArray,一个LinkedList,用来保存蛇的每 * 一节;food用来保存食物的位置;而Node类是保存每个位置的信息。 *2)重要函数: * changeDirection(int newDirection) ,用来改变蛇前进的方向,而且只是 * 保存头部的前进方向,因为其他的前进方向已经用位置来指明了。 其中newDirection * 必须和原来的direction不是相反方向,所以相反方向的值用了同样的奇偶性。在测试 * 的时候使用了direction%2!=newDirection%2 进行判断。 * moveOn(),用来更新蛇的位置,对于当前方向,把头部位置进行相应改变。如果越界, * 结束;否则,检测是否遇到食物(加头部)或身体(结束);如果什么都没有,加上头部, * 去掉尾部。由于用了LinkedList数据结构,省去了相当多的麻烦。
