+# Отчет по лабораторной работе №6
+
+Выполнила студентка гр. ИСЭбд-41 Зиновьева А. Д.
+
+## Создание приложения
+
+Было выбрано консольное приложение, язык программирования - c#.
+
+Обычный алгоритм:
+
+```cs
+static double CalculateDeterminantSequential(int[,] matrix)
+{
+ int size = matrix.GetLength(0);
+ double determinant = 0;
+
+ if (size == 1)
+ {
+ determinant = matrix[0, 0];
+ }
+ else if (size == 2)
+ {
+ determinant = matrix[0, 0] * matrix[1, 1] - matrix[0, 1] * matrix[1, 0];
+ }
+ else
+ {
+ for (int j = 0; j < size; j++)
+ {
+ determinant += matrix[0, j] * CalculateMinor(matrix, 0, j) * Math.Pow(-1, j);
+ }
+ }
+
+ return determinant;
+}
+```
+Параллельный алгоритм:
+
+```cs
+static double CalculateDeterminantParallel(int[,] matrix, int threads)
+{
+ int size = matrix.GetLength(0);
+ double determinant = 0;
+
+ if (size == 1)
+ {
+ determinant = matrix[0, 0];
+ }
+ else if (size == 2)
+ {
+ determinant = matrix[0, 0] * matrix[1, 1] - matrix[0, 1] * matrix[1, 0];
+ }
+ else
+ {
+ Parallel.For(0, size, new ParallelOptions { MaxDegreeOfParallelism = threads }, j =>
+ {
+ determinant += matrix[0, j] * CalculateMinor(matrix, 0, j) * Math.Pow(-1, j);
+ });
+ }
+
+ return determinant;
+}
+```
+
+## Бенчмарки
+
+Для примера была взята матрица размерностью 10х10, поскольку для матриц больших размеров детерминант вычисляется слишком долго.
+
+
+
+
+
+``Вывод``: Обычный (последовательный) алгоритм работает быстрее, если количество элементов не слишком много. Параллельный же алгоритм работает быстрее только при наличии большого количества операций и данных.
