mindspore.ops.bessel_k1e

mindspore.ops.bessel_k1e(x)

Computes the exponentially scaled first order modified Bessel function of the second kind for each element input.

\[\begin{split}\begin{array}{ll} \\ K_{1}e(x)= e^{(-|x|)} * K_{1}(x) = e^{(-|x|)} * \int_{0} ^{\infty} e^{-x \cosh t} \cosh (t) d t \end{array}\end{split}\]

Parameters

x (Tensor) – The input tensor.

Returns

Tensor

Supported Platforms:
