Description: LDPC码是Low Density Parity-check Codes的缩写，一个长为N的LDPC码由它的校验矩阵H来定义，该矩阵的特点是其中的元素0特别多，1特别少——即所谓的“低密度”。一个参数为（N，i，j）的H表示该矩阵中每列有i个1，每行有j个1，矩阵大小为N×K，N代表码字长度，K代表校验子的个数。
-LDPC code is the ab. of Low Density Parity-check Codes. A Length N LDPC is defined by its H matrix. The matrix has many zeros and few ones. which called \"low density\". An H matrix has a parameter as (N,i,j) express that it is the matrix which has i s 1 in each column ,j s one in each row, the size of the matrix is N*K,the N is the code word length ,k is the number of the checks.

Description: How the K-mean Cluster work
Step 1. Begin with a decision the value of k = number of clusters
Step 2. Put any initial partition that classifies the data into k clusters. You may assign the training samples randomly, or systematically as the following:
Take the first k training sample as single-element clusters
Assign each of the remaining (N-k) training sample to the cluster with the nearest centroid. After each assignment, recomputed the centroid of the gaining cluster.
Step 3 . Take each sample in sequence and compute its distance from the centroid of each of the clusters. If a sample is not currently in the cluster with the closest centroid, switch this sample to that cluster and update the centroid of the cluster gaining the new sample and the cluster losing the sample.
Step 4 . Repeat step 3 until convergence is achieved, that is until a pass through the training sample causes no new assignments. -How the K-mean Cluster workStep 1.

Description: 将正整数n表示成一系列正整数之和：n=n1+n2+…+nk，其中n1≥n2≥…≥nk≥1，k≥1。
正整数n的这种表示称为正整数n的划分。求正整数n的不同划分个数。
例如正整数6有如下11种不同的划分：
6；
5+1；
4+2，4+1+1；
3+3，3+2+1，3+1+1+1；
2+2+2，2+2+1+1，2+1+1+1+1；
1+1+1+1+1+1。-Positive integer n will be expressed as the sum of a series of positive integers: n = n1+ n2+ ...+ nk, of which n1 ≥ n2 ≥ ... ≥ nk ≥ 1, k ≥ 1. Positive integer n such that n is called the division of positive integer. For positive integer n the number of different division. Positive integer 6, for example, the following 11 kinds of different division: 6 5+1 4+2,4+1+1 3+3,3+2+1,3+1+1+1 2+2+ 2,2+2+1+1,2+1+1+1+1 1+1+1+1+1+1.

Description: 在某个音乐厅内，原始音频信号的回音由于墙壁和天花板等的反射而产生，听众所感受到的音频信号是 和它的回音的合成。令y(n)=x(n)+ax(n-k),其中x(n)=cos(0.3pin)+0.5cis(0.6pin),a=0.1,k=50.产生100个样本，使用Matlab工具，求出其自相关，从中观测确定a和k.
-In a concert hall, the original audio signal echo the walls and ceilings due to the reflection of such production, the audience felt the audio signal is and its echo synthesis. So that y (n) = x (n)+ ax (nk), where x (n) = cos (0.3pin)+0.5 cis (0.6pin), a = 0.1, k = 50. Generate 100 samples, using Matlab tools, find the self-related, from observation to determine a and k.
