WebNote that CuFFT semantics for inverse FFT only flip the sign of the transform, but it is not a true inverse. Similarly, the real to complex / complex to real variants also follow NumPy semantics and behavior. In the 1D case, this means that for an input of size N, it returns an output of size N//2+1 (it omits redundant entries, see the Numpy docs) Web陈永强，马宏，党宏杰，焦义文，刘燕都 (1.航天工程大学电子与光学工程系，北京 101416；2.北京通信与跟踪技术研究所，北京 100094)
