Acos#

  • Domain: ai.onnx

  • Since version: 22

Computes the Acos value of the input tensor element-wise.

Inputs

  • input (T): Input tensor

Outputs

  • output (T): The arccosine of the input tensor computed element-wise

Type Constraints

  • T: Constrain input and output types to float tensors. Allowed types: tensor(bfloat16), tensor(double), tensor(float), tensor(float16).

Examples#

test_cc_acos

Inputs:
  x: shape=(2, 3), dtype=float32
    [[-1.  , -0.5 ,  0.  ],
     [ 0.25,  0.5 ,  1.  ]]

Outputs:
  y: shape=(2, 3), dtype=float32
    [[3.1415927, 2.0943952, 1.5707964],
     [1.3181161, 1.0471976, 0.       ]]
