БОЛЬШАЯ ЛЕНИНГРАДСКАЯ БИБЛИОТЕКА - РЕФЕРАТЫ - Составление программы на алгоритмическом языке, выполняющей указанные преобразования с матрицамиСоставление программы на алгоритмическом языке, выполняющей указанные преобразования с матрицамиЗадание №37 Расположить в матрице A(N,N) элементы в последовательности указанной на рисунке. Требования к программе: 1. Составить программу на алгоритмическом языке, выполняющую указанные преобразования с матрицами; 2. Вывести вектор, полученный случайно; 3. Вывести преобразованную матрицу с новым содержимым вектора; 4. Программа должна строиться таким образом, чтобы существовала возможность её использования с массивами любой размерности, содержащими произвольные элементы; 5. В программе должна быть предусмотрена выдача на печать исходных и преобразованных матриц; 6. Полученные результаты должны быть занесены в файл последовательного доступа и доступны для просмотра из него.
