atan

paddle. atan ( x: Tensor, name: str | None = None ) → Tensor [source]

Arctangent Operator.

\[out = tan^{-1}(x)\]

Parameters

• x (Tensor) – Input of Atan operator, an N-D Tensor, with data type float32, float64, float16, bfloat16, uint8, int8, int16, int32, int64, complex64 or complex128.

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

Returns

Tensor. Same shape and dtype as input x

(integer types are autocasted into float32).

Examples

>>> import paddle

>>> x = paddle.to_tensor([-0.4, -0.2, 0.1, 0.3])
>>> out = paddle.atan(x)
>>> print(out)
Tensor(shape=[4], dtype=float32, place=Place(cpu), stop_gradient=True,
[-0.38050640, -0.19739556,  0.09966865,  0.29145682])
