Possibility of using vectorisation here?

Hi there - I am currently using this bit of code but it is very slow to execute, I'm sure there is a way to speed up the process through vectorisation but can't get my head around it. Does anyone have any ideas?

for i=1:4
    for j=1:365
        for k=1:24
            inds=(strcmp(cond1{i},cond) & doy==j & H==(k-1));
            count_2011(i,j,k)=sum(inds & Y==2011);
            median_2011(i,j,k)=median(dist(inds & Y==2011));
            count_2013(i,j,k)=sum(inds & Y==2013);
            median_2013(i,j,k)=median(dist(inds & Y==2013));
        end
    end
end

Many thanks in advance

You haven't included all the relevant code there. What are cond, cond1, H and Y, all of which appear to be constants, not changing inside the for loop.

I guess my point is that they are logical arrays and it was the method Iwas interested in
