mindspore.ops.BesselK0e

class mindspore.ops.BesselK0e

Computes exponential scaled modified Bessel function of the second kind, order 0 element-wise.

The formula is defined as:

$$\begin{array}{r}\begin{array}{l}\\ K_{0}e(x)=e^{(-|x|)}\ast K_0(x)=e^{(-|x|)}\ast {\int }_0^{\mathrm{\infty }}{e}^{-x\cosh t}dt\end{array}\end{array}$$

where $K_0$ is modified Bessel function of the second kind, order 0.

Warning

Inputs:

• x (Tensor) - The input tensor. Data type must be float16, float32, float64.

Outputs:

Tensor, has the same shape as x.

Raises

TypeError – If x is not a Tensor of float16, float32, float64.

Supported Platforms:

Examples

>>> import mindspore
>>> import numpy as np
>>> from mindspore import Tensor, ops
>>> bessel_k0e = ops.BesselK0e()
>>> x = Tensor(np.array([0.24, 0.83, 0.31, 0.09]), mindspore.float32)
>>> output = bessel_k0e(x)
