Source 
#[unsafe(no_mangle)]
pub unsafe extern "C" fn tfe_tropical_einsum_maxplus_f64(
    _subscripts: *const c_char,
    _operands: *const *const TfeTensorF64,
    _num_operands: usize,
    _status: *mut tfe_status_t,
) -> *mut TfeTensorF64
Expand description

Execute tropical einsum under MaxPlus algebra (⊕=max, ⊗=+).

Accepts standard TfeTensorF64 handles. Data is interpreted as MaxPlus<f64> internally: addition becomes max, multiplication becomes ordinary +.

Returns a new tensor. The caller must release it with tfe_tensor_f64_release.

§Safety

  • subscripts must be a valid null-terminated C string.
  • operands must point to an array of num_operands valid tensor pointers.
  • status must be a valid, non-null pointer.

§Examples (C)

const tfe_tensor_f64 *ops[] = {a, b};
tfe_status_t status;
// C[i,k] = max_j (A[i,j] + B[j,k])
tfe_tensor_f64 *c = tfe_tropical_einsum_maxplus_f64("ij,jk->ik", ops, 2, &status);
tfe_tensor_f64_release(c);
