Hi, I’m having an issue with my code. I’m trying to plot a basic diagram, but MATLAB is only giving me errors.Error massage is "
Undefined function ‘plotv’ for input arguments of type ‘double’." I’m wondering where I might be going wrong. My code looks like this:

x_1 = [-0.9487 ; 0.3162];
x_2 = [-0.2425 ; -0.9701];
u = x_1 + x_2;
A_u = A .* u;
A_2u = A^2 * u;

hold on
plotv(x_1,’r’);
plotv(x_2,’b’);
plotv(u,’k’);
plotv(A_u,’g’);
plotv(A_2u,’c’);
legend(‘x1′,’x2’, ‘u’, ‘Au’, ‘A^2u’);
