# scipy.sparse.kron

`scipy.sparse.``kron`(A, B, format=None)

  kronecker product of sparse matrices A and B

  Parameters : | A : sparse or dense matrix first matrix of the product B : sparse or dense matrix second matrix of the product format : string format of the result (e.g. “csr”)
  Returns : | kronecker product in a sparse matrix format :

  Examples

      >>> A = csr_matrix(array([[0,2],[5,0]]))
      >>> B = csr_matrix(array([[1,2],[3,4]]))
      >>> kron(A,B).todense()
      matrix([[ 0,  0,  2,  4],
              [ 0,  0,  6,  8],
              [ 5, 10,  0,  0],
              [15, 20,  0,  0]])

      >>> kron(A,[[1,2],[3,4]]).todense()
      matrix([[ 0,  0,  2,  4],
              [ 0,  0,  6,  8],
              [ 5, 10,  0,  0],
              [15, 20,  0,  0]])
