mindspore.ops.bessel_i0e
- mindspore.ops.bessel_i0e(x)[source]
Computes exponential scaled modified Bessel function of the first kind, order 0 element-wise.
The formula is defined as:
\[\begin{split}\begin{array}{ll} \\ \text I_{0}e(x)=e^{(-|x|)} * I_{0}(x)=e^{(-|x|)} * \sum_{m=0}^ {\infty} \frac{x^{2 m}}{2^{2 m} (m !)^{2}} \end{array}\end{split}\]where \(I_{0}\) is modified Bessel function of the first kind, order 0.
- Parameters
x (Tensor) – The input tensor. The data type must be float16, float32 or float64.
- Returns
Tensor, has the same shape and dtype as the x.
- Raises

Examples
>>> import mindspore >>> import numpy as np >>> from mindspore import Tensor, ops >>> x = Tensor(np.array([-1, -0.5, 0.5, 1]), mindspore.float32) >>> output = ops.bessel_i0e(x) >>> print(output) [0.46575961 0.64503527 0.64503527 0.46575961]
