A brief introduction to the vectorization operation and Kronecker product is shown below using matrices M,N∈Rn×n. vec(M)=[m11m21⋮mn1m12⋮mnn]whereM=[m11m12⋯m1nm21m22⋯m2n⋮⋮⋱⋮mn1mn2⋯mnn] Kronecker product is defined as shown in Eq. (A.1). It is a ...

Here, vec(X) denotes the vectorization of the matrix X formed by stacking the columns of X into a single column vector. It now follows from the properties of the Kronecker product that the equation AXB = C has a unique solution if and only if A and B are nonsingular (Horn &Johnson ...
When equipped with the Einstein product, even-order tensors with unique structures are used to model elasticity and image restoration problems. The solvability and stability of such formations are of practical importance. Of many methods, the pseudospectral way to analyze the stability of matrix equat...

We briefly define this product, and describe some of its main algebraic properties. We also briefly review the role of Kronecker products in the traditional assumption of separability of covariance functions in spatiotemporal models.Keywords:matrices;vectorization;trace;separable covariance functions;spatio...
