How to associate a range of values to a certain vector component in a if statement?

My current code looks like this:

if x(38)>=0 && x(38)<1 
    clalfaw_sec1 = clalfaw1;
    elseif x(38)>=1 && x(38)<2
        clalfaw_sec1 = clalfaw2;
    elseif x(38)>=2 && x(38)<3
        clalfaw_sec1 = clalfaw3;
    elseif x(38)>=3 && x(38)<4
        clalfaw_sec1 = clalfaw4;
    elseif x(38)>=4 && x(38)<5
        clalfaw_sec1 = clalfaw5;
end

So I wanted to clean it up so I could add variables more easily. Clalfaw is currently written as single variables, so I thought about writing it as a vector instead, and make the if cycle through it, as x(38) is on a certain range of values. But I couldn't think of any way that doesn't ends up similar to the original code. Could someone give a tip?

You can put all the clalfaws in a single array and using indexing -

arr=[clalfaw1 clalfaw2 clalfaw3 clalfaw4 clalfaw5];
idx=floor(x(38))+1;
clalfaw_sec1=arr(idx)

Aah I didn't think about using floor(), this worked perfectly, thank you!!
