    239239  Les variables aleatoires r,t sont independantes:
    240240    g(r,t) = g(r) g(t)
    241 */
     241- Attention:
     242La variable complexe "c=x+iy" ainsi definie verifie:
     243              <|c|^2> = <c c*> = <x^2+y^2> = <r^2> = 2 sig^2
     244Si on veut generer une variable complexe gaussienne telle que
     245     <c c*> = s^2 alors il faut sig = s/sqrt(2) comme argument
