Yes I know, I don't mix both, but in julia I don't know how to do it ! With your explaination I am very near, but I have this very pick, I am trying to reduce it I guess it's the resistance which is to high ? :
using Plots #pyplot(reuse=true) #plt=PyPlot R=1;L=1/pi*360E-2;C=1/(pi*360E+2);w=1/(sqrt(L*C)) f=1/(2.*pi*sqrt(L*C)) omega=2*pi*f fr=linspace(0,omega,100) y= abs(1 ./ (1+im*2*pi*fr*R*C-(2*pi*fr).^2*L*C)) #using Plots #y=abs(1./(1+im.*fr.*R.*C-fr.*fr.*L.*C)); plot(fr,y,title="Pulsation angulaire", bg=RGB(.2,.2,.2),xlabel ="Rad/s",ylabel = "Ω") Le jeudi 16 juin 2016 09:22:12 UTC+2, Henri Girard a écrit : > > 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).
