计算任意一个矩阵的模最大最小值。在matlab的m文件编程，实现(Any calculation of maximum and minimum modulus of a matrix. M-file in matlab programming,)

比较matlab中ceil()、floor()、round()等的量化误差大小。并比较不同的量化位数的误差(Compare matlab in ceil (), floor (), round (), etc. quantization error size. And comparing different error of quantization bits)

K最邻近密度估计技术是一种分类方法，不是聚类方法。 不是最优方法，实践中比较流行。 通俗但不一定易懂的规则是： 1.计算待分类数据和不同类中每一个数据的距离（欧氏或马氏）。 2.选出最小的前K数据个距离，这里用到选择排序法。 3.对比这前K个距离，找出K个数据中包含最多的是那个类的数据，即为待分类数据所在的类。(K nearest neighbor density estimation is a classification method, not a clustering method. It is not the best method, but it is popular in practice. Popular but not necessarily understandable rule is: 1. calculate the distance between the data to be classified and the data in each other (Euclidean or Markov). 2. select the minimum distance from the previous K data, where the choice sorting method is used. 3. compare the previous K distances to find out which K data contains the most data of that class, that is, the class to which the data to be classified is located.)

利用matlab读取TXT文档并显示，统计文档中某个字符出现的概率并显示，输入替换字符对文档中的某个字符进行替换。(Matlab TXT file to read and display the probability of occurrence of a certain character in the statistical document and display, enter the replacement characters to replace one of the characters in the document.)

利用matlab仿真实现在不同信道下使用不同的分集算法，以及使用不同的分集数，观察信噪比和误码率的关系，得出结论，体会分级的效果(Simulation using matlab to use different channels in different sub-set algorithm, and the use of different sub-set of the number of observed signal to noise ratio and bit error rate, concluded that the effect of experience rating)
