- scipy.sparse.kronsum(A, B, format=None)¶
kronecker sum of sparse matrices A and B
Kronecker sum of two sparse matrices is a sum of two Kronecker products kron(I_n,A) + kron(B,I_m) where A has shape (m,m) and B has shape (n,n) and I_m and I_n are identity matrices of shape (m,m) and (n,n) respectively.
