+# Отчёт по лабораторной работе №6
+
+Выполнил: студент гр. ИСЭбд-41 Михайлов Юрий.
+
+## Создание приложения
+
+Выбран язык C#.
+
+Запустим алгоритм с матрицей 10x10 c различными алгоритмами.
+

+
+
+## Бенчмарки
+
+Протекстируем обычный и паралелльный с различными размерами матриц.
+
+Матрица 3х3
+

+
+Матрица 5х5
+

+
+Матрица 10х10

+
+
+Вывод: Скоростные возможности параллельного алгоритма проявляются только при значительном количестве операций. В случае, если операций меньше, стандартный алгоритм может оказаться более быстрым.
