说明：  灰色理论认为系统的行为现象尽管是朦胧的，数据是复杂的，但它毕竟是有序的，是有整体功能的。灰数的生成，就是从杂乱中寻找出规律。同时，灰色理论建立的是生成数据模型，不是原始数据模型，因此，灰色预测的数据是通过生成数据的gm(1,1)模型所得到的预测值的逆处理结果。 此程序用来作灰色预测。 (Gray theory that the behavior of the system even though the phenomenon is dim, the data are complex, but it is after all, is orderly, there is a whole function. Gray number generation, that is, from the clutter to find out the laws. At the same time, the gray theory is to generate data model, rather than the original data model, therefore, gray forecast data to generate data through the gm (1,1) model by the inverse of the predictive value of the results. This procedure is used for gray prediction.)

关于信道仿真的源代码，内含信道模型的ppt，希望对研究信道的朋友有帮助(Channel simulation on the source code, including channel model ppt, hope that the study of channel friends have helped)

本代码对深沟球滚动轴承的滚动体做了深刻的研究，并进行了仿真分析，里面的数据来自于美国西储大学。(The rolling bearings of deep groove ball rolling, the code has made a profound study, and simulation analysis, which the data from the Case Western Reserve University in the United States.)

this code name is fast Fourier and it is used to implement the fast Fourier algorithm
