On Kronecker Products, Tensor Products And Matrix Differential Calculus [PDF]

open access: yes
The algebra of the Kronecker products of matrices is recapitulated using a notation that reveals the tensor structures of the matrices. It is claimed that many of the difficulties that are encountered in working with the algebra can be alleviated by ...
