此程序为自然梯度盲源分离，采用非线性函数-This program is a natural gradient of blind source separation, nonlinear functions

基于分离度的变步长盲源分离算法，将峭度梯度算法改进成变步长梯度算法，提高了分离性能，使收敛速度加快，使计算耗时减少。程序编入了两种算法的对比。-BSS based on separation degree by vary step gradient.

自己编的，基于自然梯度的盲源分离算法，如果想对自然梯度有所了解，可以参考Amari的经典文章。网络上一搜就行。(-own series, based on the natural gradient algorithm blind source separation, if you want to understand the natural gradient. Amari can refer to the classic article. Networks found on a trip.)
