torch (version 0.8.1)

torch_i0: I0

Description

I0

Usage

torch_i0(self)

Arguments

self

(Tensor) the input tensor

i0(input, *, out=None) -> Tensor

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

$${\text{out}}_i=I_0({\text{input}}_i)=\sum _{k=0}^{\mathrm{\infty }}\frac{({\text{input}}_i^2/4{)}^k}{(k!{)}^2}$$

Examples

if (torch_is_installed()) {

torch_i0(torch_arange(start = 0, end = 5, dtype=torch_float32()))
}
