inverse FFT

Is there an inverse FFT function in Dplot? I can't seem to find any reference to it in the manual, and the last mention of it on the forum seems to be that it was under consideration in 2009. If IFFT has not yet been included, are there plans to do so in a future update?

The trouble with an inverse FFT is both the imaginary and real parts need to be preserved. The FFT function that DPlot currently performs combines the two into a magnitude. The only good way I can see to do this is to keep the real and imaginary parts as separate curves, then allow an inverse FFT that would operate on those two curves together. I'll put it on my list, but I cannot promise a release date.

OK, thank you.
