mindspore.ops.bessel_i1e

mindspore.ops.bessel_i1e(x)[source]

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

\[\begin{split}\begin{array}{ll} \\ \text I_{1}e(x)=e^{(-|x|)} * I_{1}(x)=e^{(-|x|)} * \sum_{m=0}^ {\infty} \frac{x^{2m+1}}{2^{2m+1} m ! (m+1) !} \end{array}\end{split}\]

Parameters: x (Tensor) – The input tensor.
Returns: Tensor

Supported Platforms:: GPU CPU

Examples

>>> import mindspore
>>> x = mindspore.tensor([-1., -0.5, 0.5, 1.])
>>> output = mindspore.ops.bessel_i1e(x)
>>> print(output)
