Hello, I have a little problem to plot a function with gnuplot. here the functions (phi will be include in HNimag): phi(x) =3D atan( sin(a * pi/2) / ((2*pi*tau*x)**(-a) + cos(a * pi/2))) HNimag(x) =3D de * sin(b * phi(x)) / ((1 + 2 * (2*pi*tau*x)**(a) * cos(a =20 * pi/2) + (2*pi*tau*x)**(2*a))**(b/2)) For b=3D0.99999999999999 the trace is correct (the curve I should get =20 when b=3D1). If u take b=3D1 the function make something wrong. Is it a bug? Greetings *********************************************** Nicolas Ubrig AG Prof.Dr. Rolf Pelster Universit=E4t des Saarlandes Geb.
