盲源分离中的EASI算法，程序中提供源信号（源信号均为次高斯信号），固定的信道混合矩阵，EASI分离算法。EASI算法为定步长EASI算法，步长固定。程序中包含PI值收敛曲线程序。整体程序可以产生源信号图、混合信号图、解混信号图、PI值收敛曲线。(The EASI algorithm in the blind source separation provides the source signal (the source signal is the next Gaussian signal), the fixed channel mixing matrix, and the EASI separation algorithm. The EASI algorithm is a fixed step EASI algorithm, fixed in steps. The program contains the PI value convergence curve program. The overall program can produce the source signal map, mixed signal map, deconvolution signal graph, PI value convergence curve.)
