[Red_ Day]: Contoh Perkalian Matriks 3x3

Contoh Perkalian Matriks 3x3

catatan kuliahq:
ni source code nya bro:

#include <iostream.h>
#include <conio.h>
#include <iomanip.h>

void main()
{
    int A[3][3],B[3][3],C[3][3],i,j,k;
    clrscr();

    //masukkan matrix A
    cout<<"Silahkan input matrik A : \n";
    cout<<"------------------------- \n";
    for(i=0;i<3;i++)
    {
        for(j=0;j<3;j++)
        {
        cout<<"Elemen ke "<<(i+1)<<","<<(j+1)<<" : ";
        cin>>A[i][j];
        }
    }

    //cetak matrix A
    cout<<"\nMatrik A : \n";;
    for(i=0;i<3;i++)
    {
        for(j=0;j<3;j++)
        {
        cout<<setw(4)<<A[i][j];
        }
        cout<<endl;
    }
    cout<<endl;

    //masukkan matriks B
    cout<<"Silahkan input matrik B : \n";
    cout<<"------------------------- \n";
    for(i=0;i<3;i++)
    {
        for(j=0;j<3;j++)
        {
        cout<<"Elemen ke "<<(i+1)<<","<<(j+1)<<" : ";
        cin>>B[i][j];
        }
    }

    //cetak matrix B
    cout<<"\nMatrik B : \n";
    for(i=0;i<3;i++)
    {
        for(j=0;j<3;j++)
        {
        cout<<setw(4)<<B[i][j];
        }
        cout<<endl;
    }

    //Operasi Perkalian

for (i=0;i<3;i++)
{
    for (j=0;j<3;j++)
    {
    C[i][j]=0;
        for (k=0;k< 3;k++)
        {
            C[i][j]+= A[i][k]*B[k][j];
        }
    }
}

//Menampilkan hasil
cout<<"\nMatrik C, Hasil : \n";
for(i=0;i<3;i++)
{
    for(j=0;j<3;j++)
    {
        cout<<setw(4)<<C[i][j];
    }
    cout<<endl;
}
    cout<<endl;
    getch();

}
