2020-2-26 · Note In mathematics the Kronecker product denoted by ⊗ is an operation on two matrices of arbitrary size resulting in a block matrix. It is a generalization of the outer product (which is denoted by the same symbol) from vectors to matrices and gives the matrix of the tensor product with respect to a standard choice of basis.

• ### On Kronecker products tensor products and matrix

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 paying close attention to the indices that are concealed beneath the conventional matrix notation.
