[object Object]

[object Object][object Object]undefined[object Object]

• Description: Obtains the real number part of each element of the input tensor.

• Formula:

  $$input_i = a_i + b_i × j, where `a_i` is the real part of the complex number and `b_i` is the imaginary part of the complex number.$$ $$output_i= a_i$$

[object Object]

Each operator has calls. First, [object Object] is called to obtain the workspace size required for computation and the executor that contains the operator computation process. Then, [object Object] is called to perform computation.

• Parameters:

  • [object Object] (void *, input): memory address of the workspace to be allocated on the device.

  • [object Object] (uint64_t, input): size of the workspace to be allocated on the device, which is obtained by calling the first-phase API [object Object].

  • [object Object] (aclOpExecutor *, input): operator executor, containing the operator computation process.

• Returns:

  [object Object]: status code. For details, see .

• Deterministic computation:
  • [object Object] defaults to a deterministic implementation.
