mindspore.ops.BesselI0
- class mindspore.ops.BesselI0[source]
Computes modified Bessel function of the first kind, order 0 element-wise.
The formula is defined as:
\[\begin{split}\begin{array}{ll} \\ I_{0}(x)=J_{0}(\mathrm{i} x)=\sum_{m=0}^{\infty} \frac{x^{2 m}}{2^{2 m} (m !)^{2}} \end{array}\end{split}\]where \(J_{0}\) is Bessel function of the first kind, order 0.
