- MATRIX_SPEC (TD_DFFT2_RETURNS_TABLE)
- A matrix containing Fourier coefficients that is passed in to the TD_IDFFT2.
See Matrix Specifications and TD_DFFT2 Output.
- ART_SPEC
- An ART that was produced by the TD_DFFT2 function. The ART_SPEC is required to contain the ART_SPEC parameter TABLE_NAME,. The parameter PAYLOAD with FIELDS and CONTENT is optional. Do not use any other ART_SPEC parameters.

Name Data Type Description HUMAN_READABLE INTEGER [Dependencies: This is used when the input rows are in the raw, non-human-readable, format. The parameter is optional.]
Indicator that the DFFT2 coefficient rows are in human-readable or plottable form, or the output is in the raw form. Human- readable output is symmetric around 0, such as -3, -2, -1, 0, 1, 2, 3. Raw output is sequential, starting at zero, such as 0, 1, 2, 3.
A value of 1 means true and the output is in human readable form. A value of 0 means false and the output is in raw form. The default is 1.
ALGORITHM Enum, String [Optional] The user-defined algorithm that bypasses the internal IDFFT2 planner, and influences the IDFFT2 algorithm associated with the primary IDFFT2 calculation.
Options are COOLEY_TUKEY, or SINGLETON. The default when this parameter is not present is that the internal IDFFT2 planner selects the most efficient algorithm for the operation.
- INPUT_FMT
- No INPUT_FMT options are available for this function.
- OUTPUT_FMT
A complex number that can be in rectangular (real, imaginary) or polar (amplitude, phase) form. The output options for univariate series are the following:
- COMPLEX
- AMPL_PHASE_DEGREES
- AMPL_PHASE_RADIANS
The default is COMPLEX.
