Контрольная работа: Составление программы на алгоритмическом языке, выполняющей указанные преобразования с матрицами
Задание №37
Расположить в матрице A(N,N) элементы в последовательности указанной на рисунке.
Требования к программе:
Составить программу на алгоритмическом языке, выполняющую указанные преобразования с матрицами;
Вывести вектор, полученный случайно;
Вывести преобразованную матрицу с новым содержимым вектора;
Программа должна строиться таким образом, чтобы существовала возможность её использования с массивами любой размерности, содержащими произвольные элементы;
В программе должна быть предусмотрена выдача на печать исходных и преобразованных матриц;
Полученные результаты должны быть занесены в файл последовательного доступа и доступны для просмотра из него.
