How to store loop results where loop does not have whole numbers only

I want to store the loop results, however my loop is not only whole numbers. In the code you can see what I want to do, but it does not work, because n is not a whole number.

y = 10 
A = zeros(1,10)
for n = 4:0.5:6
A(n) = n * y
end

This does not work since e.g A(4.5) is not possible because there only positive subscripts are obviously allowed.

The easiest and most robust solution is to move those values into their own variable, defined before the loop. Then you can simply make the loop iterator the required indices:

y = 10 
V = 4:0.5:6;
A = zeros(1,numel(V))
for k = 1:numel(V)
    A(k) = V(k) * y
end

Answer 2

[Torsten]

y = 10; 
A = zeros(1,5);
iCount = 0;
for n = 4:0.5:6
iCount = iCount + 1;
A(iCount) = n * y
end
