Hi all,
I need to perform a correlation using Fourier Transform. The correlation for two functions g and h is:
F[Corr(g,h)] = [F(g)]* . F(h)
the asterisk denotes the complex conjugate. My doubt is about how to calculate the complex conjugate for the first transformation and after that, how multiply them.
I have 2 TH2D histograms representing g and h.
Thanks in advance,
Manuel
