The result series is a series with the same content type as the original SERIES_SPEC. A univariate input returns a univariate output, and a multivariate input returns a multivariate output.
RETURNS TABLE Schema
This function returns a primary result set (ARTPRIMARY). Depending on the OUTPUT_FMT used in the function, the Fourier Coefficients returned are complex numbers in either rectangular or polar forms.
In the following table, dominant_payload_name depends on the input source payload content type. If the input source payload content type is COMPLEX or MULTIVAR_COMPLEX, then the payload name is associated with the complex components in rectangular form. If the input source payload content is AMPL_PHASE or MULTIVAR_AMPL_PHASE, then the payload name is associated with the complex component in polar form.
