Error using plot Vectors must be the same lengths.

I am getting error as,

Error using plot
Vectors must be the same lengths.

Error in plot(v,I,'r');

My code:

clc;
clear all; 
close all;
w=1;
i=1;
M1=2e6;
M2=2e9;

for t=0:0.2:4*pi

      v(i)=2*sin(w*t);

          if (v(i)>=1.5)

          M = M1;

          if (v(i)<-1.5)

          M = M2;

          end 

            I(i)= v(i)/M;
            i=i+1;    
          end

end

figure;
plot(v,I,'r');

Can anyone help me.

Thank you in advance

If you put your code into the MATLAB editor and highlight it and ask for Smart Indent, then if you look at the indentation it should be obvious where your code is wrong.
