I have multiple datasets of time series.
each time series is 256 points
A=220k time series
B= set C + set D 79k time series
C=29k time series
D=50k time series
F= 2*set B
Ok so here is where it gets wierd.
I take the FFT of all these set, A’ B’…
and everything appears to be normal
but then when i take the iFFT it takes very different times,
(numbers are ~averages over a few runs each)
does anyone have any tips or pointers to figure out that this may be?
