- ValueColumns
- Specifies the names of one to 16 inputtable columns that contain the signal values on which to perform IFFT.
- NumDimensions
- [Optional] Specifies the number of dimensions in the signal. The parameter dimensions must be the INTEGER value 1, 2, or 3. (A time series has one dimension; an image has two or three.) Default: 1.
- FFTLength
- [Optional] Specifies the maximum signal length. The parameter FFT_length must be an INTEGER. Default: 224. If the signal length exceeds FFT_length, the function truncates it to FFT_length.In a signal with more than one dimension, each dimension must have the same length.
- OutputPolarCoordinates
- [Optional] Specifies whether to output polar coordinates—(magnitude, phase). Default: 'false'.
- InputPolarCoordinates
- [Optional] Relevant only if IsSignalRealValued is 'true'. Specifies whether to read complex numbers as polar coordinates—(magnitude, phase). Default: 'false'.
- PadNonPowerOfTwoLengths
- [Optional] Specifies whether to pad the input signal with zeros to round up to the closest power of two. Default: 'true'. If you specify 'false', the function truncates the input signal and rounds down to the closest power of 2 dimensions that is less than the input signal.
- IsSignalRealValued
- [Optional] Specifies whether the value columns contain REAL (DOUBLE PRECISION) values. Default: 'true'. If you specify 'false', the function interprets the values as complex numbers; therefore, they must be multiples of two.
