[object Object]

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

• Description: Performs element-wise cosine operation.

• Formula:

  $$x = [{x_0}, {x_1}, ... {x_{n-1}}]\\ y = [{y_0}, {y_1}, ... {y_{n-1}}]\\$$ $${\rm y}_i = \cos(x_i) (i=0,1,...n-1)$$

• Example

  1. The input [object Object] is [–1, –2] with dtype [object Object].
  2. Call the [object Object] operator.
  3. The output [object Object] is [0.5403, –0.4161] with dtype [object Object].

[object Object]

Each operator has calls. First, aclnnForeachCosGetWorkspaceSize is called to obtain the input parameters and compute the required workspace size based on the process. Then, aclnnForeachCos is called to perform computation.

• The input value range of [–65504, 65504] satisfies functional precision requirements; precision is not guaranteed for values outside this range.
• Deterministic computation:
  • aclnnForeachCos defaults to a deterministic implementation.
