Hi, When I make my plots I have two plots, but before I hadn't this... w is the resoning frequency, but it should appear at 0 (zéro) not at extrem ? Any help, I already ask for help with pyplot, this link : https://groups.google.com/forum/#!topic/julia-users/EJSvutfdEus, which works fine for angular pulsation, but I want frequency resonance with Plots because I guess I can make more beautifull graphic (anyway I don't know well PyPlot or Plots). I succeeded once with pyplot but after an error I couldn't find it back ! Bad luck :) Kind regards HG
using Plots pyplot(reuse=true) z=10;u=0.02;s=0.02;w=1/(2*pi*sqrt(u*s)) f=linspace(-30,30) y=abs(1./(1+im.*f.*z.*s-f.*f.*u.*s)); #fig = figure("Angle") plot(f, y)
