Hi, I sometimes time expressions with a left argument of something like 10 or 100, e.g. "(100) 6!:2 'singlePair testSP0'". This gives me an average time for the multiple iterations. It would be nice to be able to get the standard deviation of the multiple invocations as well.
I can do this myself with something like tms=. 6!:2 &>100$<'singlePair testSP0' then doing statistics on "tms" but I'm wondering if there's a way to do this more simply. tms=. 6!:2 &>100$<'singlePair testSP0' (mean,stddev) tms 0.260937 0.00313815 Thanks, Devon -- Devon McCormick, CFA Quantitative Consultant ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
