Did you finish with the first, non-matlab part (mathematical model)?

i have to model in two directions

1. in the x direction; simulate mixing proportional to sqrt Dv
2. in the y direction; simulate mixing proportional to
(u.L)^2/ Dv.

this is the code i have come up with so far.....its not much

np=1000;nt=3000 ('np=no. of particle, nt=no. of time steps')
u=input ('velocity of particle')
Dv=input ('transverse diffusion coefficient')
L=sqrtDv
x(1:np,1)=0;y(1:np,1)=0
for i=2:nt
s=rand(np,1)

thats all ive done.....i need to model the x & y directions. any suggestion?
