What's wrong with my code? (first matlab code) picture attached!!

I was trying to do an assignment problem using matlab. It's an engineering problem where I had to calculate the drag coefficient, and then use the equation drag=(Cd*r*(V^2)*A)/2 to calculate the drag at different velocities and creating a table. But it gives me an error message as you can see. Can someone please tell me what's wrong with it?

In your ‘Table’ variable assignment, you transposed ‘V’ from a (1x11) row vector to a (11x1) column vector. You cannot horizontally concatenate that with a scalar value for ‘drag’.

This will work:

V = 0:20:200;
r = 1E-6;
A = 1;
Cd = 2.0019E+6;

drag = (Cd*r*(V.^2)*A)/2;

Table = [V' drag'];
