torch_digamma: Digamma

In torch: Tensors and Neural Networks with 'GPU' Acceleration

Digamma

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.

\psi(x) = \frac{d}{dx} \ln\left(\Gamma\left(x\right)\right) = \frac{\Gamma'(x)}{\Gamma(x)}

Examples

if (torch_is_installed()) {

a = torch_tensor(c(1, 0.5))
torch_digamma(a)
}
