一个直方图均衡化的小程序。具体为比较均衡化图象与非均衡化图象的不同。(a histogram equalization of small programs. Specific for a more balanced image of a non-balanced images are different.)

亲测，很好用的hash function(Pro-test, a good hash function used)

灰色预测GM(1，1)，结合之前数据，并根据之前数据之间内在关系，预测发展方向(Grey Prediction GM (1,1), combined with previous data, and in accordance with the intrinsic relationship between the data before predicting the direction of development)

改程序勇于特征降维。使用PCA的方法降低特征维度(Courage to change the feature dimension reduction program. Use PCA method to reduce the dimension feature)

The book launches around two main contents: antenna and radio wave propagation. The book consists of 14 chapters. The first nine chapters are the antenna section, which includes the basic knowledge of antenna, simple wire antenna, traveling wave antenna, non-frequency-varying antenna, slot antenna and microstrip antenna, mobile phone antenna, direction finding antenna, surface antenna and new type antenna, and the last five chapters are the radio wave propagation section, which includes the basic knowledge of radio wave propagation, the ground. Wave propagation, sky wave propagation, line of sight propagation, and prediction of received field strength in ground mobile communication.)

说明：  Ode 方程解法，主要用于网站收敛,这一算福安非常的好(numerical integration for ODE for the web site convergence)
