- scipy.sparse.kronsum(A, B, format=None)[source]#
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.
- Parameters
- A
square matrix
- B
square matrix
- formatstr
format of the result (e.g. “csr”)
- Returns
- kronecker sum in a sparse matrix format
