extra i in formula in guide?

Tuesday, 7 May 2013

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
