此函数是根据柯西分布概率密度函数和累积分布函数的概念而编写的matlab程序，并附有一个测试程序。(This function is based on the Cauchy distribution probability density function and cumulative distribution function of the concept and write matlab program, together with a test program.)

说明：  基于MATLAB的有源滤波器的实现，很简单，能看懂。(The realization of active filter based on MATLAB is simple and understandable.)

说明：  这是基于matlab下的数字信号处理示例，包括信号、系统和系统响应的实现等(These are some digtal signal processing examples based on the matlab. And these include filter ,matrax algthrom,and so on......)

点云三维重建，用matlab写成的，效果很好，而且速度也比较快(Point cloud reconstruction, written with matlab, works well, but speed is faster)

PLS算法的matlab程序实现，只要将txt中的代码复制到matlab即可-PLS (algorithm matlab program, simply txt the code can be copied to matlab)

that is useful code for communication

这是有关matlab结课作业，是我们几个同学集体努力做得论文，也许对大家有用。(This is the matlab Guitar Lesson operations, is our collective efforts of several students doing papers, and perhaps useful to everyone.)

说明：  利用蒙特卡洛方法来计算信噪比与误码率的关系(Monte carlo method is used to calculate the relationship between SNR and bit error rate)

幂法是一种计算矩阵主特征值（矩阵按模最大的特征值）及对应特征向量的迭代方法，特别适用于大型稀疏矩阵。 但是，一般幂法迭代向量v的各个不等于零的分量将随k 趋向于无穷大而使计算机溢出。因此，我们必须对某通幕法进行规范。即规范化幂法 (Power Method is a calculation of the main eigenvalue matrix (matrix according to the largest eigenvalue modulus) and the corresponding eigenvector of the iterative method, especially for large sparse matrix. However, the general power-law iteration vector v is not equal to zero all the components will be as k tends to infinity overflow of the computer. Therefore, we must pass a law to regulate screen. That is, standardized Power Method)
