paddle / acos
acos¶
-
paddle.acos( x, name=None ) ¶
arccosine函数。
\[out = cos^{-1}(x)\]
- 参数:
-
x (Tensor) - 输入的Tensor，数据类型为：float32、float64。
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。
返回类型： Tensor
代码示例：
import paddle
x = paddle.to_tensor([-0.8183, 0.4912, -0.6444, 0.0371])
res = paddle.acos(x)
print(res)
# [2.5293, 1.0573, 2.2711, 1.5336]
