SparseTensorDenseMatMul

tensorflow C++ API

tensorflow::ops::SparseTensorDenseMatMul

Multiply SparseTensor (of rank 2) “A” by dense matrix “B”.

Summary

No validity checking is performed on the indices of A. However, the following input format is recommended for optimal behavior:

if adjoint_a == false: A should be sorted in lexicographically increasing order. UseSparseReorderif 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).

Arguments:

  • scope: AScope object
  • a_indices: 2-D. Theindicesof theSparseTensor, size[nnz, 2]Matrix.
  • a_values: 1-D. Thevaluesof theSparseTensor, size[nnz]Vector.
  • a_shape: 1-D. Theshapeof theSparseTensor, size[2]Vector.
  • b: 2-D. A dense Matrix.

Optional attributes (seeAttrs):

  • 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).

Returns:
