Description

Digamma

Usage

torch_digamma(self)

Arguments

self

(Tensor) the tensor to compute the digamma function on

digamma(input, out=NULL) -> Tensor

Computes the logarithmic derivative of the gamma function on input.

ψ(x) = \frac{d}{dx} \ln≤ft(Γ≤ft(x\right)\right) = \frac{Γ'(x)}{Γ(x)}

Examples

if (torch_is_installed()) {

a = torch_tensor(c(1, 0.5))
