Create loop with variable pitch

Hello very good, I wondered if anyone would know how to create a for loop with variable pitch, the idea is as follows:

I would have to go through the positions 1 3 5 5.5 6 6.5 7 9. what I know is to use two bubles

for i=1:2:9
...
end

for i=5.1:0.5:6.9
...
end

Would there be any way to do it in one loop? Thank you very much.

for i=[1 3 5 5.5 6 6.5 7 9]
...
end

thank you very much, but well the interval I had set is just an example, the real is much greater and write it by hand would not be a good solution.

Any other ideas?

What is the pattern that your data follows because if they do not follow a regular pattern you must place them manually, if they have a regular pattern then what would it be?
