Was that the first time you ran meanfilter?Doesn't the second time run faster?
No that was the third time.In the test below I cheated a little bit and created the filter (f) before I called tic, so this will also affect time.
Thanks, Søren
Thanks, I hadn't thought of that implementation - it's nice :-) Unforunaly it doesn't appear to be fast enough: a = rand(1,100000); f = ones(1,100)/100; tic; m1 = meanfilter(a, 100); toc ans = 0.15448 tic; m2 = conv(a, f); toc ans = 0.12615 Thanks, Søren
