The Main Diagonal of a Permutation Matrix This paper is about banded doubly infinite permutation matrices. These matrices represent permutations of the integers Z, in which no integer moves more th... M Lindner,G Strang 被引量: 0发表: 0年...
Setting the API key in this way should mean that the API key is always accessible by the RDistanceMatrix package in every new R session. If the API key cannot be found after closing and opening a new R session, we can set it manually using:...

Polynomials of the Adjacency Matrix of a Graph (distance-Transitive, Distance-Regular, Orbit) Given graphs (GAMMA) and (DELTA), and a real polynomial r(x), we will say that (DELTA) is generated from (GAMMA) by r(x) if r(A((GAMMA))) = A((DELTA)) wher... RA Beezer 被引量: ...
For the example, we use the distance matrix D above to obtain ca = (1/1 + 1/1 + 1/1 + 1/1 + 1/2)/5 = 27/30, cb = 17/30, cc = 21/30, cd = 24/30, ce = 21/30, cf = 20/30. Node a does not only have many connections and to other central nodes, but it is ...
We start with the matrix in Figure 4.3(a), where the xi are listed on the left and the yj at the top. Note that we have added x0 and y0, two null characters at the start of x and y, to simplify the implementation. Specifically, this allows us to quickly fill in the first row...
When the tree has no vertex of degree 2, the formula is particularly simple and depends on a certain “two-step” Laplacian of the tree. We determine the inertia of Δ. The inverse and the inertia of the edge orientation matrix are also described.R.B. Bapat...
Using eq. (30.4), one obtains the similarity matrix in Table 30.4. Because the matrix is symmetrical, only half of this matrix needs to be used. Table 30.3. Example of a data matrix SystemConcentrations (arbitrary units) Metal aMetal bMetal cMetal d A 100 80 70 60 B 80 60 50 40 C...
