[object Object]

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

• Description: Computes the hyperbolic function of the input tensor based on a specific formula and returns a new tensor. The shape of the output tensor is identical to that of the input tensor.
• Formula:$$out=cosh(self)$$

[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 stored in the memory of the input tensor.

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