Hi all, I have two files here, one in smath, one in mathcad. The mathcad file is calculated about 1000 times faster, does anyone have a tip how to speed up the .sm file?  ts.sm (20kb) downloaded 32 time(s). ts.xmcd (61kb) downloaded 7 time(s).

By setting the formulas with the numeric optimization option switches from 29s to 19s. Still away from your expectations

OFF topic of the speed, I don't understand your histogram. Histogram take raw data from collection, ultimately to get a PDF. Cheers ... Jean. Stat Histogram DEMO.sm (24kb) downloaded 7 time(s). Stat Histogram QUICK.sm (58kb) downloaded 7 time(s).

Hi Jean, Sorry for the delay, unfortunately I found no time... I have attached my histogram again, revised it a bit and commented it. Actually I think it does exactly what it should, but I have to admit that I don't know the exact definition of a histogram 8) Histogram_JP.sm (19kb) downloaded 15 time(s).And again about the speed: I played a little with my definition of "rnorm" and come to the strange result that my vector is calculated fastest when I calculate it in pieces of 20 elements. I would be happy if a more experienced user could explain this to me. speed.sm (18kb) downloaded 10 time(s).Have a nice weekend! Johannes
