[object Object]

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

• Function: performs the arccosine operation on each element of the input matrix and outputs the result.

• Formula:

  $$out_{i}=cos^{-1}(input_{i})$$

[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 aclnnAcosGetWorkspaceSize or aclnnInplaceAcosGetWorkspaceSize to obtain the workspace size required for computation and the executor that contains the operator computation process, and then call aclnnAcos or aclnnInplaceAcos to perform the computation.
