- scipy.sparse.kronsum(A, B, format=None)[source]#
- kronecker sum of square 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
