Imag
(dims, dtype='complex128')[source]¶ Imag operator.
Return the imaginary component of the input as a real value. The adjoint returns a complex number with zero real component and the imaginary component set to the real component of the input.
Parameters: Notes
In forward mode:
\[y_{i} = \Im\{x_{i}\} \quad \forall i=0,\ldots,N-1\]In adjoint mode:
\[x_{i} = 0 + i\Re\{y_{i}\} \quad \forall i=0,\ldots,N-1\]Attributes: Methods
