方法一:两两比较 这个题目如果按照题目意思解答,求出矩阵的所有对角线,情况很复杂。所以使用的是直接两两进行比较的方式。 判断每行元素的每个元素和其右下角的元素是否相等,如果不等就返回False;全部相等返回True. class Solution(object): def isToeplitzMatrix(self, matrix): """ :type matrix: List[List[in...
Hi, I have a dataset with 35 banks (N) and 2600 trading days (T) each, and I want to test for cross-sectional dependence (which should be there in theory). However, I get the message: Correlation matrix of residuals is singular. not possible with test, r(131); I already searched ...
An adaptive filter based on singular‐value decomposition of input signal correlation matrix 来自 国家科技图书文献中心 喜欢 0 阅读量: 42 作者:Y Kikuchi,T Saito 摘要: The characteristics of the proposed adaptive filter were investigated, and a computer simulation of the filter as a noise canceller...
For a singular correlation matrix some or all of the images degenerate into the original variates, and the corresponding anti‐images have zero variance. It is suggested that these images and anti‐images be replaced with variates (pseudo‐images and pse
A SVD-based(Singular Value Decomposition-based) enumeration method of Hankel matrix of the spatial correlations of sensor outputs is proposed for the ULA(Uniform Linear Array). Utilizing the general form of Hankel matrix of sensor array with the exclusion of the term of the unknown noise ...
