cudaFFT()

void cudaFFT	(	CUstream_st *	stream,
		int	nx,
		int	ny,
		cufftDoubleComplex *	in_filed,
		cufftDoubleComplex *	output_field,
		int	direction,
		bool	bNormalized
	)

Convert data from the spatial domain to the frequency domain using 2D FFT on GPU.

call CUDA Kernel - fftShift and CUFFT Library.

Parameters

stream	: CUDA Stream
nx	: the number of column of the input data
ny	: the number of row of the input data
in_field	: input complex data variable
output_field	: output complex data variable
direction	: If direction == -1, forward FFT, if type == 1, inverse FFT.
bNormalized	: use normalize
