        for i=0:10
            d=sum(i+)
            .
            .
            .
            .

I think timer is likely to give you better precision for this sort of thing than tic/toc (tic/toc is better for timing performance of a function or script). The reference page for timer illustrates exactly this while-loop scenario.
