torch.view_as_real#

torch.view_as_real(input)→Tensor#

Returns a view ofinput as a real tensor. For an input complex tensor ofsize$m1,m2,\dots ,mi$m1,m2,…,mi, this function returns a newreal tensor of size$m1,m2,\dots ,mi,2$m1,m2,…,mi,2, where the last dimension of size 2represents the real and imaginary components of complex numbers.

Warning

view_as_real() is only supported for tensors withcomplexdtypes.

Parameters:

input (Tensor) – the input tensor.

Example:

>>>x=torch.randn(4,dtype=torch.cfloat)>>>xtensor([(0.4737-0.3839j), (-0.2098-0.6699j), (0.3470-0.9451j), (-0.5174-1.3136j)])>>>torch.view_as_real(x)tensor([[ 0.4737, -0.3839],        [-0.2098, -0.6699],        [ 0.3470, -0.9451],        [-0.5174, -1.3136]])
