no line on graph

I am relatively new to matlab and am trying to figure things out.

I tried the following script but the graph shows no lines. the absolute value of x1/x2 is a function of w.

Can anyone help?.........Thank you in advance!!!

clc

clear

m1=550;

m2=300;

w=linspace(0,10,1000);

k1=60;

k2=50;

k3=40;

A=(-m1*w.^2 + k1 +k3);

B=k3;

C=k3;

D=(-m2*w.^2 + k2 +k3);

E=(B*C)-(A.*D);

P0=1000;

K=P0

x1=K*(-D./E);

x2=K*(C./E);

X=abs(x1/x2)

plot(w,X,'g')

You vectorised everything else, and then forgot to vectorise the division in your ‘X’ assignment:

X=abs(x1./x2);
        ↑        

Your code now plots your line.

Thank you!

I've noticed with writing code, it is the little details that make a difference....
