The Kronecker product operator is used in the discretization of the governing equations and the boundary conditions. The eigenvalue problem is solved to obtain the natural frequencies.doi:10.1016/j.ijmecsci.2012.03.008Elsevier LtdInternational Journal of Mechanical Sciences...
distributions as follows:(2)p(u|G,A)=N(0,G⊗A), where G is the m×m (co)variance matrix of the polygenic effects across m traits, A is the additive genetic relationship matrix that can be obtained from the pedigree of all individuals, and ⊗ is the Kronecker product operator.(...
The Kronecker product,kron(X,Y), of two matrices is the larger matrix formed from all possible products of the elements ofXwith those ofY. IfXism-by-nandYisp-by-q, thenkron(X,Y)ismp-by-nq. The elements are arranged such that each element ofXis multiplied by the entire matrixY: ...

Kronecker productHadamard productPositive definite matrixGeometric meansweighted geometric meansIn this paper, a family of geometric means for positive matrices is studied; we discuss possible definitions of the geometric means of positive matrices, and some counter examples are given. It is still an ...
Third, the necessary and sufficient conditions under which equalities occur are presented. Thereby, we generalize two inequalities involving the Khatri–Rao product.关键词: Matrix inequality Khatri-Rao product Tracy-Singh product Hadamard product Kronecker product Schur complement 被引量: 8 年份: 2002 ...
Let\(\varvec{A}\in \mathbb R ^{m\times n}\)and\(\varvec{B}\in \mathbb R ^{p\times q}\)then theKronecker productis the\(mp\times nq\)-matrix: $$\begin{aligned} \varvec{A}\otimes \varvec{B} = \begin{pmatrix} a_{11}\varvec{B}&\cdots&a_{1n}\varvec{B} \\ \v...
where L ¯ ∗ ( t ) = L ¯ ( t ) + B ¯ ( t ) and “⊗” is the Kronecker product operator. Then, the convergence of z ˜ is shown by the following lemma. Lemma 1 (Lemma 2 in [28]). Under Assumption 4, ∀ l i > 0 , the state z ˜ ( t ) of the...
where 𝑖=1,2,3i=1,2,3; the Kronecker delta 𝛿𝑖,1δi,1 is 1 for i=1 and 0 otherwise. Just to bring out the importance of the technological constraints for the maximization of overall welfare, we simplify Equation (24) slightly by using a function of decreasing marginal utility ...
, and the stokes operator s is an unbounded, self-adjoint, positive definite operator with respect to the \([l^2(\omega )]^n\) inner product. thus, the stokes eigenvalue problem can be rewritten as $$\begin{aligned} s{{\mathbf {u}}}_k =\lambda _k {{\mathbf {u}}}_k, \end...
