plot a complex number

Hi,

can anyone help me please to plot a complex number with real and imaginary parts on a same figure. the complex number is as below: -37.18+1.74i

here is my code:

w1 = 1.37*10^16                          %w1 is plasma frequency of gold in Hz%
w2 = linspace (21.99*10^14,1.37*10^16)            %w2 is X frequency in Hz%
e1 = 1-(w1).^2./(w2).^2                     %e1 is real part of 
e3 = (w1.^2)./(w2).^3
e2 = e3*10^14
n  = complex (e1,e2)

Many Thanks

Two possibilities, depending on how you want to depict it:

figure(1)
plot(w2,real(n), w2,imag(n))
grid
xlabel('w_2')
legend('Re','Im','Location','SE')

figure(2)
subplot(2,1,1)
plot(w2,abs(n))
grid
ylabel('Ampitude')
subplot(2,1,2)
plot(w2,angle(n)*180/pi)
grid
xlabel('w_2')
ylabel('Phase (°)')
