· 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.
