mindspore.ops.bessel_k1e
- mindspore.ops.bessel_k1e(x)[source]
Computes exponential scaled modified Bessel function of the second kind, order 1 element-wise.
The formula is defined as:
\[\begin{split}\begin{array}{ll} \\ K_{1}e(x)= e^{(-|x|)} * K_{1}(x) = e^{(-|x|)} * \int_{0} ^{\infty} e^{-x \cosh t} \cosh (t) d t \end{array}\end{split}\]where \(K_{1}\) is modified Bessel function of the second kind, order 1.
- Parameters
x (Tensor) – The input tensor. The data type must be float16, float32 or float64.
- Returns
Tensor, has the same shape and dtype as the x.
- Raises
- Supported Platforms:

Examples
>>> import mindspore >>> import numpy as np >>> from mindspore import Tensor, ops >>> x = Tensor(np.array([0.5, 1., 2., 4.]), mindspore.float32) >>> output = ops.bessel_k1e(x) >>> print(output) [2.73100971 1.63615349 1.03347685 0.68157595]
