+# Лабораторная работа №5 - Алгоритмы перемножения матриц
+
+## Описание
+Были реализованы 2 алгоритма для перемножения больших матриц: обычный и параллельный. Для тестирования производительности обоих алгоритмов
+был установлен пакет BenchmarkDotNet.
+
+## Прохождение tutorials:
+
+# Параметры
+Mean: Среднее время выполнения одного теста.
+
+StdErr (Standard Error): Погрешность среднего времени выполнения.
+
+N: Количество измерений — 98. Чем больше N, тем точнее статистические результаты.
+
+StdDev (Standard Deviation): Стандартное отклонение.
+
+Min и Max: Минимальное и максимальное зафиксированные значения.
+
+ConfidenceInterval: Доверительный интервал для среднего значения. Это диапазон, в который с высокой вероятностью попадёт среднее значение, если провести ещё одну серию тестов.

+
+Общий результат
+![результат работы](./images/image4.jpg)
+
+## Вывод
+По общему результату мы можем сделать вывод, что Параллельный алгоритм быстрее обычного за счет того, что он распределяет вычисления по нескольким потокам, что позволяет выполнять разные части задачи одновременно.
+
+## Отчет
+Работоспособность: [Видео](https://vk.com/video372869030_456239958?list=ln-gxUH2mdzTSJOvos5g3)
