The incidence matrix can be applied only to directed graph only. The number of entries in a row apart from zero tells us the number of branches linked to that node. This is also called as degree of that node. The rank of completeincidence matrixis (n-1), where n is the number of ...
Consider using a decision matrix when there are several factors vying for your attention. It can help you to establish priorities and rank your criteria to arrive at the best possible decision. When to use a decision matrix (and when not to) A decision matrix can help you not only make co...
The theoretical maximum link setup rate can be reached only when the rank of the H matrix is n and each row vector or column vector is not closely related. This poses a great challenge to the antenna design of APs. In some tests, the link setup rate between the two ends of a Wi-Fi...
If you're only comparing one or two differences, you probably don't need a decision matrix. Can I assign a level of relative importance or impact to each of the weighted criteria? You should be able to comfortably rank each option based on the numerical scale discussed in this guide. If...
aUsing the notions of rank, condition number, size and the SVD, we can analyse whether or not the matrix is singular, how many independent columns exist, what columns are dependent and to what degree. 使用等级、情况数字、大小和SVD的概念,我们可以分析是否矩阵是单一的,多少个独立专栏存在,什么专...
