Using index to name variables

I'm running a script with a index containing:
t{1} = Location1;
t{2} = Location2;
t{3} = Location3;
tt{1} = "Location1";
tt{2} = "Location2";
tt{3} = "Location3";
t's are tables. Now the actual script does e.g. this:
for x = 1:1:size(t{n})
if t{n}.var1(x) == 0
a_tt{n}(x) = b_tt{n}(x) / t{n}.var2(x);
if t{n}.var2(x) == 0
a_tt{n}(x) = 0;
end
As can be seen above I am trying to get a_Location1 and b_Location2 - but it does not work that way. Is there a smooth way to get a_location1/2/3 and b_location1/2/3 using the index?
It's for a lot of lines in the script, so some way without doing it by hand, would be nice!
Thanks for your help!

Why do you want numbered variables? You shouldn't store data in a variable name.

Do not create variables names dynamically. This would store information in the names, where it is hard to access. Use the values of the variables instead.
You can use dynamic field names of structs:
a = struct()
for x = 1:1:size(t{n})
if t{n}.var1(x) == 0
a.(tt{n})(x) = b_tt{n}(x) / t{n}.var2(x);
elseif t{n}.var2(x) == 0
a.(tt{n})(x) = 0;
end
end
