[Insight-developers] fill

[M.Staring at lumc.nl]

Hi Bill,

Good question, see the attached file for some timings. So for small sizes std::fill_n is actually slower. There seems to be a startup cost involved for std::fill. On the other hand, filling such small arrays does not take a lot of time anyway, and I don't think that is done in a big loop. Or am I wrong there?

Regards, Marius

What do the timings look like for small array size, e.g. 3, 4... ITK uses Fill() to initialize sizes, indexes, points, etc. which are small.
