2D Inverse Multi-channel FFT (DBL)

	shift? specifies whether the DC component is at the center of each channel of Multi-channel FFT {X}. The default is FALSE.
	Multi-channel FFT {X} specifies frequency-domain sequences by rows or columns.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	FFT direction specifies whether to perform inverse FFT on each row of Multi-channel FFT {X} or each column of Multi-channel FFT {X}. 0 Row-wise (default)—Each row of Multi-channel FFT {X} is one channel frequency-domain sequence. Specifies that this VI performs inverse FFT on each row of Multi-channel FFT {X}. 1 Column-wise—Each column of Multi-channel FFT {X} is one channel frequency-domain sequence. Specifies that this VI performs inverse FFT on each column of Multi-channel FFT {X}.
	X returns the inverse FFT result of each channel in Multi-channel FFT {X}.
	error out contains error information. This output provides standard error out functionality.
