a = [2 3
4 5
6 7
9 8]
out = 1 + (diff(a,1,2)>0)
OR
[~,out] = max(a,[],2)

I did not get the use case of the question however , the following code does exactly what u need. Hope this helps.
cnt=1;
a=[2,3,4,5,6,7,9,8];
for i = 1:2:length(a)
if(a(i)>a(i+1))
b(cnt)=1;
else
b(cnt)=2;
end
cnt=cnt+1;
end

Note that you should not use i as the loop variable, as this is the name of the inbuilt imaginary unit . This is poor coding practice in MATLAB.
