如何使用 C# 执行矩阵加法?
要执行矩阵加法,需要两个矩阵。输入矩阵一和矩阵二的行和列。记住,两者的矩阵都应是方阵才能相加。
现在给两个矩阵添加元素。声明一个新数组,并添加这两个数组。
arr3[i, j] = arr1[i, j] + arr2[i, j];
让我们看看完整的代码 −
示例
using System; using System.Linq; class Demo { static void Main() { int m, n, i, j; Console.Write("Enter number of rows and columns of the matrix "); m = Convert.ToInt16(Console.ReadLine()); n = Convert.ToInt16(Console.ReadLine()); int[,] arr1 = new int[10, 10]; int[,] arr2 = new int[10, 10]; int[,] arr3 = new int[10, 10]; Console.Write("Enter elements - Matrix 1 : "); for (i = 0; i < m; i++) { for (j = 0; j < n; j++) { arr1[i, j] = Convert.ToInt16(Console.ReadLine()); } } Console.Write("Enter elements - Matrix 2 : "); for (i = 0; i < m; i++) { for (j = 0; j < n; j++) { arr2[i, j] = Convert.ToInt16(Console.ReadLine()); } } Console.WriteLine("Matrix 1 "); for (i = 0; i < m; i++) { for (j = 0; j < n; j++) { Console.Write(arr1[i, j] + "\t"); } Console.WriteLine(); } Console.WriteLine("Matrix 2 "); for (i = 0; i < m; i++) { for (j = 0; j < n; j++) { Console.Write(arr2[i, j] + "\t"); } Console.WriteLine(); } for (i = 0; i < m; i++) { for (j = 0; j < n; j++) { arr3[i, j] = arr1[i, j] + arr2[i, j]; } Console.WriteLine(); } Console.WriteLine("Matrix Addition "); for (i = 0; i < m; i++) { for (j = 0; j < n; j++) { Console.Write(arr3[i, j] + "\t"); } Console.WriteLine(); } Console.ReadLine(); } }
输出
以下为输出。
Enter number of rows and columns of the matrix 3 3 Enter elements - Matrix 1 : 1 2 3 4 5 6 7 8 9 Enter elements - Matrix 2 : 1 2 3 4 5 6 7 8 9 Matrix 1 123 456 789 Matrix 2 123 456 789 Matrix Addition 246 81012 141618
