C# Program to perform Matrix Multiplication
You are Here:
Perform Matrix Multiplication
In the following example, we will multiply the two given matrices (two-dimensional arrays).
Example
C# Compiler
using System;
namespace myApp
{
class Program
{
static void Main(string[] args)
{
int i, j, k;
int[,] arr1 = {
{1, 1, 1},
{1, 1, 1},
{1, 1, 1}
};
int[,] arr2 = {
{2, 2, 2},
{2, 2, 2},
{2, 2, 2}
};
int[,] arr3 = new int[3, 3];
Console.WriteLine("Matrix A (3 x 3):");
for(i=0; i<3; i++)
{
for(j=0; j<3; j++)
Console.Write("{0} ", arr1[i, j]);
Console.WriteLine();
}
Console.WriteLine("\nMatrix B (3 x 3):");
for(i=0; i<3; i++)
{
for(j=0; j<3; j++)
Console.Write("{0} ", arr2[i, j]);
Console.WriteLine();
}
for(i=0; i<3; i++)
{
for(j=0; j<3; j++)
{
for(k=0; k<3; k++)
arr3[i, j] = arr3[i, j] + arr1[i, k] * arr2[k, j];
}
}
Console.WriteLine("\nMatrix Multiplication (A x B):");
for(i=0; i<3; i++)
{
for(j=0; j<3; j++)
Console.Write("{0} ", arr3[1, 1]);
Console.WriteLine();
}
}
}
}
Output
Matrix A (3 x 3):
1 1 1
1 1 1
1 1 1
Matrix B (3 x 3):
2 2 2
2 2 2
2 2 2
Matrix Multiplication (A x B):
6 6 6
6 6 6
6 6 6
