Metodi pubblici
Uscita pubblica <T> asOutput ()
Restituisce l'handle simbolico del tensore.
Gli input per le operazioni TensorFlow sono output di un'altra operazione TensorFlow. Questo metodo viene utilizzato per ottenere un handle simbolico che rappresenta il calcolo dell'input.
Metodo factory per creare una classe che racchiude una nuova operazione Ifft2d.

Uscita pubblica <T> uscita ()
Un tensore complesso della stessa forma di "input". Le 2 dimensioni più interne di "input" vengono sostituite con la loro trasformata di Fourier 2D inversa.
