paddle / cosh
cosh¶
-
paddle.cosh( x, name=None ) ¶
双曲余弦函数。
输入范围是 (-inf, inf) ， 输出范围是 [1,inf]。
\[out = \frac{exp(x)+exp(-x)}{2}\]
- 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
x = paddle.to_tensor([-0.4, -0.2, 0.1, 0.3])
out = paddle.cosh(x)
print(out)
# [1.08107237 1.02006674 1.00500417 1.04533851]
