Angular pulsation with pyplot works as whishes :
using PyPlot
plt=PyPlot
R=40;L=1/pi*360E-2;C=1/(pi*360E+2);ω=1/(sqrt(L*C))
fr=linspace(0,2ω)
y=abs(1./(1+im.*fr.*R.*C-fr.*fr.*L.*C));
fig = figure("Angle")
plt.plot(omega, y);
plt.ylabel("z");
plt.xlabel("w");
ax = plt.gca() # get current axes
ax[:set_xlim]((50,500));
ax[:set_ylim]((0,10));
plt.grid("on")
plt.title("Pulsation angulaire");
round(ω)
I am doing it with plots ...
But I wish frequency resonance with plots (or even pyplot because I didn't
make it work properly).
