对周围相邻的 8 邻居求和（元胞只有两种状态，0 或 1 ）。元胞也有一个单独的状态参量（所谓 记录 ）记录它们之前是否有非零状态的邻居。 在 0 与 1 之间产生一个随机数 r 。 如果总和> 0 （至少一个邻居）并且 r >阈值，或者元胞从未有过一个邻居，则元胞= 1 。 如果总和> 0 则设置"记录"的标志，记录这些元胞有一个非零的邻居。 (8 adjacent neighbors on the surrounding sum (cell only two states, 0 or 1). Cell also has a separate state parameters (so-called ' records' ) record that they have non-zero state before the neighbors. Between 0 and 1 generate a random number r. If the sum of> 0 (at least one neighbor) and r> threshold, or the cell has never had a neighbor, then cell = 1. If the sum> 0 set the " record" sign, record the cell has a non-zero neighbors.)

无偏灰色预测模型的实现，直接改数据即可运行。(Unbiased gray prediction model to achieve, directly change the data to run.)

this is matlab code for ICA

获取理想频段内的信号，这样就有助于进行相应的信号处理工作(The ideal band for the signal, so that helps to make the appropriate signal processing)
