mindspore.ops.bessel_k0

mindspore.ops.bessel_k0(x)

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

\[\begin{split}\begin{array}{ll} \\ K_{0}(x)= \lim_{\nu \to 0} \left(\frac{\pi}{2}\right) \frac {I_{-\nu}(x)-I_{\nu}(x)}{\sin (\nu \pi)} = \int_{0}^{\infty} e^{-x \cosh t} d t \end{array}\end{split}\]

Parameters

x (Tensor) – The input tensor.

Returns

Tensor

Supported Platforms:
