说明：  迭代算法的收敛率p是等于矩阵导数的最大特征根,Jacobi矩阵表示的是信息缺失的比例,所以p是一个可以有效的表示缺失信息的一个比例的标量,缺失信息的比例其实就是单位矩阵I 减去已经观测到的信息占完全信息的比例(The convergence rate P of the iterative algorithm is equal to the maximum characteristic root of the matrix derivative. Jacobi matrix represents the proportion of missing information, so P is a scalar that can effectively represent a proportion of missing information. The proportion of missing information is actually the proportion of the unit matrix I minus the observed information to the complete information.)
