mindspore.ops.BesselI0e
- class mindspore.ops.BesselI0e[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.

Examples
>>> import mindspore >>> import numpy as np >>> from mindspore import Tensor, ops >>> bessel_i0e = ops.BesselI0e() >>> x = Tensor(np.array([0.24, 0.83, 0.31, 0.09]), mindspore.float32) >>> output = bessel_i0e(x) >>> print(output) [0.7979961 0.5144438 0.75117415 0.9157829 ]
