(or SparseTensor) "B". Please note that one and only one of the inputs MUST be a SparseTensor and the other MUST be a dense matrix.

The following input format is recommended (but not required) for optimal performance:

  • If adjoint_a == false: A should be sorted in lexicographically increasing order. Use sparse.reorder if you're not sure.
  • If adjoint_a == true: A should be sorted in order of increasing dimension 1 (i.e., "column major" order instead of "row major" order).

sp_a SparseTensor (or dense Matrix) A, of rank 2.
b dense Matrix (or SparseTensor) B, with the same dtype as sp_a.
adjoint_a Use the adjoint of A in the matrix multiply. If A is complex, this is transpose(conj(A)). Otherwise it's transpose(A).
adjoint_b Use the adjoint of B in the matrix multiply. If B is complex, this is transpose(conj(B)). Otherwise it's transpose(B).
name A name prefix for the returned tensors (optional)

A dense matrix (pseudo-code in dense np.matrix notation): A = A.H if adjoint_a else A B = B.H if adjoint_b else B return A*B
