Hi,
I would like to transform this python working example into a ijulia program
,
Any help
HG
var("w")
u=1/pi*360;s=1/(pi*360)
R=100;L=10;C=10E-6
w=1/(sqrt(L*C));var('omega')
p=plot(abs(1/(1+i*omega*R*C-omega*omega*L*C)),omega,0,2*w,figsize=4,frame=True,
fontsize=8,axes=False,color="green") ;show(p)
print"Pulsation angulaire = ",round(w)," Rad/s"
I tried this but got errors :
R=100;L=10;C=10E-6;w=1/(sqrt(L*C));omega=0;
x=linspace(0,2pi)
y=(abs(1/(1+im*omega*R*C-omega*omega*L*C)));
fig = figure("Angle")
plt.plot(x, y);
plt.ylabel("z");
plt.xlabel("w");
ax = plt.gca() # get current axes
ax[:set_xlim]((0,2*w));
ax[:set_ylim]((0,10));
plt.grid("on")
plt.title("Pulsation");
LoadError: PyError (:PyObject_Call) <type 'exceptions.ValueError'>
