What is the best way to execute 2 if conditions in MATLAB

assume w=[1 2 2 2]
       q=[2 1 1 1]
if w(i)==1 
do somehing
else 
look to q(i)
if q(i)==1
do some thing
else
do somthing
end 
end

Answer 1

[José-Luis]

for ii = 1:numel(w)
    if (w(ii) == 1)
        %stuff
    else if (q(ii) == 1)
        %stuff
    else
        %stuff
    end
end

Please accept an answer if it helps you.

Thanks for your answer.I just want to know about the third statement,will the program check w or q .I guess w? Thanks

[José-Luis]

It will check nothing. It will run that bit only if any of the first two conditions are not satisfied.
