1.2. Интерполяционные формулы для равноотстоящих узлов
Если
значения функции
заданы в точках
с постоянным положительным шагом, то
часто используется интерполяционный
многочлен Ньютона для интерполяции
вперед
,
(1.10)
где
,
а конечные разности
,
носящие названия нисходящих
разностей, находят из соотношений
,
.
Интерполяционный
многочлен (1.10) удобно использовать при
работе в начале таблицы значений функции
и для экстраполяции левее точки
.
Интерполяционный
многочлен с узлами
где
,
имеет вид
(1.11)
и
называется интерполяционным многочленом
Ньютона для интерполяции назад. Его
удобно использовать при интерполяции
в конце таблицы и для экстраполяции
правее точки
.
Входящие в выражение (1.11) значения
конечных восходящих разностей находят
из соотношений
,
..............................................
.
Если
при заданном
в таблице значений функции
с шагом
имеется достаточное число узлов с каждой
стороны от
,
то целесообразно узлы интерполяции
выбрать так, чтобы точка
оказалась как можно ближе к середине
минимального отрезка, содержащего узлы.
При этом обычно в качестве
берется ближайший к
узел, затем за
принимается ближайший к
узел, расположенный с противоположной
от
стороны, чем
.
Следующие узлы назначаются поочередно
с разных сторон от
и должны быть расположены как можно
ближе к
.
Одной из возможных схем интерполяции
в этом случае является схема Стирлинга
с интерполяционным многочленом вида
В
этом выражении учитывается, что дано
нечетное число
значений функции
,
где
.
Обычно эту формулу целесообразно
использовать при
.
