can anyone explain cuConjf()?

hello everyone,

I have:

cufftComplex G
and
cufftComplex F

now i need the fft(G)*conj(fft(F))

so i calculated both FFT’s ( G’ and F’)
but now i have to get the conjugate of F’

i found something about cuConjf() on the forums but i cant seem to find the right way to use it.

anyone have some help?

Thanks
