[object Object]

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

• Description: Performs the inverse hyperbolic cosine operation on each element of the input tensor and outputs the result.

• Formula:

  $$out=cosh^{-1}(self)$$

[object Object]

• [object Object] and [object Object] implement the same function in different ways. Select a proper operator based on your requirements.
  • [object Object]: An output tensor object needs to be created to store the computation result.
  • [object Object]: No output tensor object needs to be created, and the computation result is written in place to the input tensor's memory.
• Each operator has calls. First, [object Object] or [object Object] is called to obtain the workspace size required for computation and the executor covering the operator computation process. Then, [object Object] or [object Object] is called to perform computation.
