Kronecker productsequationsSummary We consider two arbitrary matrices not necessarily square. The ordinary matrix product of two conformable matrices is denoted by A 路 B ; the numbers of columns of A and rows of B must match. The Kronecker product of these two matrices is denoted. Properties ...
Kronecker积(Kronecker Product) Kronecker积是两个矩阵的张量积,记作A⊗B。具体来说,如果A是m×n矩阵,B是p×q矩阵,则A⊗B是一个mp×nq的矩阵,其元素由以下公式给出: (A⊗B)i,j=Ai′,j′Bi″,j″ 其中i=(i′−1)p+i″且j=(j′−1)q+j″,1≤i′≤m,1≤j′≤n,1≤i″≤p,1...

By Kronecker product, the matrix equation (1) is equivalent to the linear system Ax=c, where A=Is⊗A+B⊤⊗In is an ns×ns matrix, x and c are two ns-dimensional vectors formed by the columns of X and C. However, this linear system is costly to solve because the dimension of...

Note that we want to apply the Laplacian matrix to the u and v coordinates at the same time, thus we need to extend it taking the left Kronecker product with a 2x2 identity matrix: SparseMatrix<double> L_flat; repdiag(L,2,L_flat); The area matrix is computed with igl::vector_...
Denote by δ the N-periodic Kronecker symbol, i.e. δ(n)=1 if n≡0mod(N), and δ(n)=0 otherwise. Set [x]=N−1(1−xN)/(1−x). The elementary building blocks of the basic state sums are the N2×N2-matrix valued quantum dilogarithms and their inverses, whose matrix ...
