increase a value each iteration

hi frieds, i guess this is more a math question than programming, but i have this problem, i would like to increase dy a variable y each n iteration values, por example,

i have nmax iteration

nmax=50;

i have diferential values of y

dy=.5

so i do a loop

for i=1:nmax

y(i)= and my question is here. ??
end

so i want an output like

y(1)=0
y(2)=.5
y(3)=1

so on until 50 iteration, so my question is a funcion y(i) that give me a vector of dy increments but in function of i. thanks for advance

may be

   y=0:0.5:(50*0.5)
