torch (version 0.14.2)

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.

$$ \mbox{out}_{i} = I_0(\mbox{input}_{i}) = \sum_{k=0}^{\infty} \frac{(\mbox{input}_{i}^2/4)^k}{(k!)^2} $$

Examples

if (torch_is_installed()) {

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