How to subtract two matrices (matrix) in C#

Answer 1

using System;

public class Program
{
	public static void Main(string[] args)
	{
		int[][] matrix1 = new int[][] {
			new int[] {1, 2, 3, 4},
			new int[] {5, 6, 7, 8},
			new int[] {9, 7, 6, 3}
		};
		int[][] matrix2 = new int[][] {
			new int[] {1, 1, 1, 1},
			new int[] {2, 2, 2, 2},
			new int[] {3, 3, 3, 3}
		};
		int[][] sub = new int[][] {
			new int[] {0, 0, 0, 0},
			new int[] {0, 0, 0, 0},
			new int[] {0, 0, 0, 0}
		};

		int rows = matrix1.Length;
		int cols = matrix1[0].Length;

		for (int i = 0; i < rows; i++) {
			for (int j = 0; j < cols; j++) {
				sub[i][j] = matrix1[i][j] - matrix2[i][j];
			}
		}

		for (int i = 0; i < rows; i++) {
			for (int j = 0; j < cols; j++) {
				Console.Write(sub[i][j] + " ");
			}
			Console.WriteLine();
		}
	}
}
