add
(A: dgl.sparse.sparse_matrix.SparseMatrix, B: dgl.sparse.sparse_matrix.SparseMatrix) → dgl.sparse.sparse_matrix.SparseMatrix[source]¶ Elementwise addition for
SparseMatrix
, equivalent toA + B
.- Parameters
A (SparseMatrix) – Sparse matrix
B (SparseMatrix) – Sparse matrix
- Returns
Sparse matrix
- Return type
Examples
>>> indices = torch.tensor([[1, 0, 2], [0, 1, 2]]) >>> val = torch.tensor([10, 20, 30]) >>> A = dglsp.spmatrix(indices, val) >>> B = dglsp.diag(torch.arange(1, 4)) >>> dglsp.add(A, B) SparseMatrix(indices=tensor([[0, 0, 1, 1, 2], [0, 1, 0, 1, 2]]), values=tensor([1, 20, 10, 2, 33]), shape=(3, 3), nnz=5)
