entropy

This file contain the Simulation of a Cognitive Radio System by Using Matlab Software.Also This file containing a guide file to explain how the code is work.

内容：空间目标识别，采用PM算法。程序中附有注释，可以改变方向角，运算速度比music算法快，本人毕设程序，绝对可用。(Content: space target recognition using PM algorithm. Annotated program, you can change the direction of the angle calculation algorithm is faster than the music, I set up the program, absolutely free.)

你见过 MATLAB 最早的版本吗？下载一份 MATLAB 1.0,(只有182K, 只有20来个函数) 体会一下吧。MATLAB早期表示矩阵是用 <> 而不是 []。 (Have you seen the first version of MATLAB you? Download a MATLAB 1.0, (only 182K, only 20 to a function) experience yourself. MATLAB is a matrix of early that < > instead of [].)

threshold is a key technique for the segmentation and edge detection in an image for image processing. Here in this file the threshold is on the based of the maximum entropy of an image using shannon entropy method.
