How to create a vector based on another vector in a for loop?

I would like to create a vector based on another vector, how do i do that? Is it easiest to do so with a for loop? Below is the code that i have so far. But it doesn't seem to be working. What am I missing?

for Vp=[0:0.2:4];
    u=Vp/A
end

Vp=0:.2:4;
A=5;
u=Vp/A;

[David Hill]

Vp=0:.2:4;
A=5;
for k=1:length(Vp)
    u(k)=Vp(k)/A;
end
