How to take a given value from a table in a function?

Hello,

For example I have a table given

I calculate a=y/l , For example a=y/l=2 so i need to get g=0.2.

If i get a=y/l=1 (Out of the table) it should be equal g=0.2. Also in the bottom a=y/l=6 => g=0.5.

I did it in function and does not succeed.

Thanks for the helpers

function [g] = func(y, l)

a=y/l
end
