mindspore.ops.BesselK1e
- class mindspore.ops.BesselK1e[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.

Examples
>>> import mindspore >>> import numpy as np >>> from mindspore import Tensor, ops >>> bessel_k1e = ops.BesselK1e() >>> x = Tensor(np.array([0.24, 0.83, 0.31, 0.09]), mindspore.float32) >>> output = bessel_k1e(x) >>> print(output) [ 4.9821286 1.8675754 4.0140023 12.008413 ]
