Kronecker product. 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.
