Разложение полинома по кубической и квадратич- ным параболам

Abstract

Получена новая форма разложения полинома Pn(x) по базисным элементам трём квадратичным и одной кубической параболами. Базисные элементы определяются через x-координаты, связанные специальным правилом сложного отношения четырёх точек. В задачах полиномиальной аппроксимации и сглаживания такое разложение позволяет повышать эффективность и качество вычислений.
