torch (version 0.8.1)

torch_polar: Polar

Description

Polar

Usage

torch_polar(abs, angle)

Arguments

abs

(Tensor) The absolute value the complex tensor. Must be float or double.

angle

(Tensor) The angle of the complex tensor. Must be same dtype as abs.

polar(abs, angle, *, out=None) -> Tensor

Constructs a complex tensor whose elements are Cartesian coordinates corresponding to the polar coordinates with absolute value abs and angle angle.

$$ \mbox{out} = \mbox{abs} \cdot \cos(\mbox{angle}) + \mbox{abs} \cdot \sin(\mbox{angle}) \cdot j $$

Examples

if (torch_is_installed()) {

abs <- torch_tensor(c(1, 2), dtype=torch_float64())
angle <- torch_tensor(c(pi / 2, 5 * pi / 4), dtype=torch_float64())
z <- torch_polar(abs, angle)
z
