mindspore.ops.bessel_i0

mindspore.ops.bessel_i0(x)[source]

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

\[\begin{split}\begin{array}{ll} \\ I_{0}(x)=J_{0}(\mathrm{i} x)=\sum_{m=0}^{\infty} \frac{x^{2 m}}{2^{2 m} (m !)^{2}} \end{array}\end{split}\]

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_i0(x)
>>> print(output)
