PERKALIAN MATRIKS MENGGUNAKAN ARRAY


PERKALIAN 2 MATRIKS MENGGUNAKAN ARRAY
 
  1.   Perkalian matriks ordo 2x2 manual
#include<iostream>
using namespace std;
int main () {
            int A[2][2]={{1,2},{3,4}};
            int B[2][2]={{5,6},{7,8}};
            int c,d;
            int w,x,y,z;
            cout<<endl;
            cout<<"Matriks A"<<endl;
            for(c=0;c<2;c++){
                        for(d=0;d<2;d++){
                                    cout<<"    "<<A[c][d];
                        }
                        cout<<endl;
            }
            cout<<endl;
            cout<<"Matriks B"<<endl;
            for(c=0;c<2;c++){
                        for(d=0;d<2;d++){
                                    cout<<"    "<<B[c][d];
                        }
                        cout<<endl;
            }
            cout<<endl;
            cout<<"Perkalian Matriks AxB"<<endl;
            w=((A[0][0]*B[0][0])+(A[0][1]*B[1][0]));
            x=((A[0][0]*B[0][1])+(A[0][1]*B[1][1]));
            y=((A[1][0]*B[0][0])+(A[1][1]*B[1][0]));
            z=((A[1][0]*B[0][1])+(A[1][1]*B[1][1]));
            cout<<"    "<<w<<"    "<<"    "<<x<<endl;
            cout<<"    "<<y<<"    "<<"    "<<z;
}

22.   Perkalian matriks dengan di input
