acos

paddle. acos ( x, name=None ) [source]

Acos Activation Operator.

\[out = cos^{-1}(x)\]
Parameters
  • x (Tensor) – Input of Acos operator, an N-D Tensor, with data type float32, float64, float16, complex64 or complex128.

  • name (str, optional) – Name for the operation (optional, default is None). For more information, please refer to Name.

Returns

Tensor. Output of Acos operator, a Tensor with shape same as input.

Examples

>>> import paddle

>>> x = paddle.to_tensor([-0.4, -0.2, 0.1, 0.3])
>>> out = paddle.acos(x)
>>> print(out)
