PS: Подскажите где подглядеть "правильный" и желательно быстрый алгоритм подсчёта FWHM? Хочу прикрутить к PI.
Цитата: NKV от 29 Ноя 2011 [11:56:10]PS: Подскажите где подглядеть "правильный" и желательно быстрый алгоритм подсчёта FWHM? Хочу прикрутить к PI.В книжке AIP4WIN. Пардон, с вычислением барицентра попутал.Но, думаю, и про FWHM-ы там тоже что-то есть.
