how to plot a function?

Im trying to plot 'd' as a function of variable 'me' from 0 to 1200 but just get a straight line. Any suggestions? Thanks.

mc = 1000;
Sp = 4000;
Se = 400000;
Sc = 0.2;
eff = 0.6;
v = 13.41;

me = 0:1200;

d = ((Se*me*(Sp-(Sc*v)))/(Sc*Sp*(mc+me)))*eff;

plot(me,d,'x')

You need to vectorise the division (use (./) instead of (/):

d = ((Se*me*(Sp-(Sc*v)))./(Sc*Sp*(mc+me)))*eff;
                        ↑ INSERT ‘.’ HERE

See Array vs. Matrix Operations (link) for details.
