Remove the numbers before you commands.

Check that your parentheses are lining up the way you intend. Your first plot command has a mismatched number of opening and closing parentheses. Syntax should be plot(x,y)

plot(V_X(1,:)),((V_X(2,:)),'k')
             ^  ^ remove these ones

You use a lot of unnecessary parentheses. Removing these makes it easier to spot mismatches.

figure
plot(V_X(1,:),V_X(2,:),'k')
hold on 
title('--------',int2str(n))
plot(matrixV(1,:),matrixV(2,:),'--r*')
hold off
