mindspore.ops.bessel_k0

mindspore.ops.bessel_k0(x)

Computes the zeroth order modified Bessel function of the second kind for each element input.

$$\begin{array}{r}\begin{array}{l}\\ K_0(x)=\underset{\nu \to 0}{lim}\left(\frac{\pi }{2}\right)\frac{I_{-\nu }(x)-I_{\nu }(x)}{\sin (\nu \pi )}={\int }_0^{\mathrm{\infty }}{e}^{-x\cosh t}dt\end{array}\end{array}$$

Parameters

x (Tensor) – The input tensor.

Returns

Tensor

Supported Platforms:
