cos( x, name=None )
Warning: API “paddle.fluid.layers.layer_function_generator.cos” is deprecated since 2.0.0, and will be removed in future versions. Please use “paddle.cos” instead.
Cosine Operator. Computes cosine of x element-wise.
Input range is (-inf, inf) and output range is [-1,1].
\(out = cos(x)\)
x (Tensor) – Input of Cos operator, an N-D Tensor, with data type float32, float64 or float16.
name (str, optional) – Name for the operation (optional, default is None). For more information, please refer to Name.
Output of Cos operator, a Tensor with shape same as input.
- Return type
import paddle x = paddle.to_tensor([-0.4, -0.2, 0.1, 0.3]) out = paddle.cos(x) print(out) # [0.92106099 0.98006658 0.99500417 0.95533649]
