[Gretl-devel] extra i in formula in guide?
Hi Jack (I guess this goes to you...),
in the Fourier transform definition in section 6.5 of the guide,
am I correct in thinking that there is one i too many? I mean, plugging in
the definition of $\omega(j,k) = 2 \pi i jk/n$ into the formula which contains
$e^{-i\omega(j,k)}$, we get two i instead of one, right?
thanks,
sven
