- Diberikan suatu matriks berordo n. Buatlah algoritma dan program untuk mencetak matriks identitas berodo n.
source code :
#include"iostream"
using namespace std;
main(){ int i,j,n;
cout<<"masukkan ordo matriks : "; cin>>n;
for(i=1;i<=n;i++){
for(j=1;j<=n;j++){
if(i==j) cout<<"1 ";
else cout<<"0 ";
}
cout<<endl;
}
}
- Buatlah program untuk menghasilkan transpose suatu matriks.
source code :
#include
<iostream>
using namespace std;
main(){ int i,j,m,n,o;
cout<<"Program transpose matriks C(m,n)\nMasukkan nilai m : ";
cin>>m; cout<<"masukkan nilai n : "; cin>>n;
int mat[m][n];
for(i=0;i<m;i++){
for(j=0;j<n;j++){
cout<<"nilai C("<<i+1<<","<<j+1<<")=";
cin>>mat[i][j];
}
cout<<endl;
}
system("cls");
cout<<"matriks diatas diilustrasikan seperti gambaran dibawah ini\n\n";
for(i=0;i<m;i++){
for(j=0;j<n;j++){
cout<<mat[i][j]<<" ";
}
cout<<endl;
}
o=m; m=n; n=o;
cout<<"\nTranspose matriksnya adalah seperti gambar dibawah ini\n\n";
for(j=0;j<m;j++){
for(i=0;i<n;i++){
cout<<mat[i][j]<<" ";
}
cout<<endl;
}
}
using namespace std;
main(){ int i,j,m,n,o;
cout<<"Program transpose matriks C(m,n)\nMasukkan nilai m : ";
cin>>m; cout<<"masukkan nilai n : "; cin>>n;
int mat[m][n];
for(i=0;i<m;i++){
for(j=0;j<n;j++){
cout<<"nilai C("<<i+1<<","<<j+1<<")=";
cin>>mat[i][j];
}
cout<<endl;
}
system("cls");
cout<<"matriks diatas diilustrasikan seperti gambaran dibawah ini\n\n";
for(i=0;i<m;i++){
for(j=0;j<n;j++){
cout<<mat[i][j]<<" ";
}
cout<<endl;
}
o=m; m=n; n=o;
cout<<"\nTranspose matriksnya adalah seperti gambar dibawah ini\n\n";
for(j=0;j<m;j++){
for(i=0;i<n;i++){
cout<<mat[i][j]<<" ";
}
cout<<endl;
}
}
- Buatlah program mengalikan matriks dengan suatu skalar (konstanta).
