[complex] torch.polar accepts negative values for abs argument #52919
Description
>>> abs_t = torch.tensor([-1., 2, -3])
>>> angle_t = torch.randn(3)
>>> torch.polar(abs_t, angle_t)
tensor([-0.7947-0.6070j, 1.2734-1.5422j, -2.6964+1.3151j])It should error out if abs<0.
We should add checks in the following kernel
