该程序不使用matlab自带的程序，自主编写，进行简单更改可以实现多中功能，算法思想是滤波器的实现！(The program does not use matlab own procedures, self-writing, more than a simple change in function can be achieved, the algorithm idea is the realization of filters!)

用MATLAB产生高斯白噪声的算法。该历程用的是产生标准正态分布的高斯白噪声(Use MATLAB to create Gaussion White Noise)
