mindspore.ops.bessel_i0

mindspore.ops.bessel_i0(x)

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

$$\begin{array}{r}\begin{array}{l}\\ I_0(x)=J_0(\mathrm{i}x)=\sum _{m=0}^{\mathrm{\infty }}\frac{x^{2m}}{2^{2m}(m!{)}^2}\end{array}\end{array}$$

Parameters

x (Tensor) – The input tensor.

Returns

Tensor

Supported Platforms:
