Run a for loop for three different types of excitation

I need to run a for loop for three different scenarios. I tried this: -

 etyp = 3 %number of excitation types
 for i = 1:etyp
    if i = 1
        excitation = 'noise';
    end
    if (i = 2)
        excitation = 'mls';
    end
    if (i = 3)
        excitation = 'sweptsine';
    end
 end

but I get an error that I don't understand. Could anyone explain what's wrong with this code? Thanks

worked it out

equals signs for the ifs need to be doubles i.e. ==
