[object Object]

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

• Function: performs the inverse hyperbolic cosine operation on each element in 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 is divided into two phases (../common/Two-Phase Interface.md). You must call aclnnAcoshGetWorkspaceSize or aclnnInplaceAcoshGetWorkspaceSize to obtain the workspace size required for computation and the executor that contains the operator computation process, and then call aclnnAcosh or aclnnInplaceAcosh to perform computation.
