cos¶

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

Cosine Operator. Computes cosine of x element-wise.

Input range is (-inf, inf) and output range is [-1,1].

\[out = cos(x)\]

Parameters

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

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

Returns

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

(integer types are autocasted into float32).

Examples

>>> import paddle

>>> x = paddle.to_tensor([-0.4, -0.2, 0.1, 0.3])
>>> out = paddle.cos(x)
>>> print(out)
Tensor(shape=[4], dtype=float32, place=Place(cpu), stop_gradient=True,
[0.92106098, 0.98006660, 0.99500418, 0.95533651])
