代码说明:

1、统计任意文本文件中各字符(区分大小写)数量,计算字符概率,并计算信源熵。 2、香农编码       任意输入消息概率,利用香农编码方法进行编码,并计算信源熵和编码效率。 3、费诺编码       任意输入消息概率,利用费诺编码方法进行编码,并计算信源熵和编码效率。 4、哈夫曼编码      任意输入消息概率,利用哈夫曼编码方法进行编码,并计算信源熵和编码效率。

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

  • pil_sdo
    An efficient algorithm for identification of PIL on Solar Dynamic Observatory (SDO) Helioseismic and Magnetic Imager (HMI) magnetograms. Detailed description will appear in the paper: Volobuev, D.M. Polarity-Inversion Line Preceding X-class Flare, Solar Physics, Initial data (65 megabyte .fits magnetograms) can be downloaded from http://hmi.stanford.edu/ - Model_test_PIL_Open.m script - calculates parameters of the example(simulated S-curve) - SDO_PIL_Open.m script - identifies PIL on SDO magnetogram and calculates its parameters - 5 functions are used within these scripts
