Plotting a complex function with function in real and imag part

I am abit lost while trying to plot a complex function when it comes to a function that with a function in real and imag part

Let say the f=x+i*y, where f,x,y are functions of w, and i is an imaginary number.

the range of w is

w=0:0.1:50;

I tried to use

plot(w,f)

and matlab told me that either real part/ imag part has been ignored in the graph

and I tried to use

plot(w,real(f),imag(f))

and system shows error...

I am confused how can I plot this equation with defining the w and with the range of w from 0~50... and how can I plot the graph correctly...

I do appreciate your help in advance!

[Mehmed Saad]

figure,plot(w,real(f)) hold on,plot(w,imag(f))

or

figure,plot(w,[real(x);imag(x)])

Thank you so much!!! it works!
