mindspore.ops.Polar

class mindspore.ops.Polar

Converts polar coordinates to Cartesian coordinates.

Returns a complex tensor, its elements are Cartesian coordinates constructed with the polar coordinates which is specified by radial distance abs and polar angle angle.

Refer to mindspore.ops.polar() for more details.

$$y_i=ab{s}_i\ast \cos (angl{e}_i)+ab{s}_i\ast \sin (angl{e}_i)\ast j$$

Warning

This is an experimental API that is subject to change.

Inputs:

• abs (Tensor, float) - Radial distance. Tensor of any dimension, with dtype required to be float32.

• angle (Tensor, float) - Polar angle. It has the same shape and dtype as abs.

Outputs:

Tensor, with the same shape as abs and the dtype is complex64.

Supported Platforms:

Ascend GPU CPU
