I. Решение систем линейных уравнений методом Гаусса с выбором главного элемента.
II. Соглашение о требованиях:
* Программа предназначена для нахождения корней систем линейных уравнений с вещественными коэффициентами.
* Ввод данных осуществляется при помощи заполнения соответствующих полей на форме.
III. Описание программы:
* Язык программы Visual С++.
* Математическая постановка задачи:
Дано: Система линейных уравнений
a11x0 + a12x1 + ... + a1nxn = b1 ,
a21x0 + a22x1 + ... + a2nxn = b2 ,
. . . . . . . . . . . . .
an1x0 + an2x1 + ... + annxn = bn
Найти: корни данной системы используя метод Гаусса для систем линейных уравнений с выбором главного элемента.
* Математическое решение:
Метод Гаусса с выбором главного элемента по всей матрице (схема полного выбора). В этой схеме допускается нарушение естественного порядка исключения неизвестных.
На 1-м шаге метода среди элементов aij определяют максимальный по модулю элемент ai1j1. Первое уравнение системы и уравнение с номером i1 меняют местами. Далее стандартным образом производят исключение неизвестного xi1 из всех уравнений, кроме первого.
На k-м шаге метода среди коэффициентов aij(k-1) при неизвестных в уравнениях системы с номерами i = k, ..., n выбирают максимальный по модулю коэффициент aikjk(k-1). Затем k-е уравнение и уравнение, содержащее найденный коэффициент, меняют местами и исключают неизвестное xjk из уравнений с номерами i = k + 1, ..., n.
На этапе обратного хода неизвестные вычисляют в следующем порядке: xjn, xjn-1, ..., xj1.
