提供函数能进行1维2维的FFT，输入输出的序列长度应为2的整数次方倍(Provides functions can be one-dimensional two-dimensional FFT, sequence length input and output should be an integer power of 2 times)

随机数生成程序，该随机数呈zipf分布，就是大家常说对于内容的访问遵循80/20原则，也就是20 的内容，会占有80 的访问量。(Random number generator, the zipf was distributed random numbers, that is, we often say that the access to the content to follow the 80/20 principle, which is 20 of the content will occupy 80 of visits.)

利用ARIMA处理分析时间序列，计算数列相关性和数字特征并通过计算所得值进行一定范围的预测(ARIMA processing analysis time sequence, to calculate a number of columns and digital characterized by the calculated value for a certain range of the prediction)
