yes and or nod?

Im trying to make a graph of the locations of particles as they change over time but whenever I use scatter it gives me the error X and Y must be vectors of the same length Im sure its something simple, im not that good at matlab

Your Xx and Xy are matrices......you want to plot a surface? Or what you are expecting?

[KSSV]

Dude..you need reconsider your code.......

   fx = 6.*pi.*rho_f*v.*R.*(u-u_p);

u_p is of size 1600*1.

In your code, X and Y are not vector. It is matrix with size 1600 x 7. You can use below comment.

if true
  scatter(Xx(:,7),Xy(:,7))
end
