paddle / cos
cos¶
-
paddle.cos( x, name=None ) ¶
余弦函数。
输入范围是 (-inf, inf) ， 输出范围是 [-1,1]。
\[out = cos(x)\]
- 参数:
-
x (Tensor) - 输入的Tensor，数据类型为：float32、float64 、float16。
name (str，可选） - 操作的名称(可选，默认值为None）。更多信息请参见 Name。
返回：输出Tensor，与 x 维度相同、数据类型相同。
代码示例：
import paddle
import numpy as np
x = paddle.to_tensor([[-1, np.pi], [1, 15.6]], dtype='float32')
res = paddle.cos(x)
print(res)
# [[ 0.54030231 -1. ]
# [ 0.54030231 -0.99417763]]
