mindspore.ops.bessel_k0e

mindspore.ops.bessel_k0e(x)

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.

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

• TypeError – If x is not a Tensor.

• TypeError – If dtype of x is not float16, float32 or float64.

Supported Platforms:

GPU CPU

>>> 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_k0e(x)
