 1 #include <bits/stdc++.h>
 2 #define ll long long
 3 using namespace std;
 4 int H, W, h, w;
 5 
 6 int main(){
 7     cin >> H >> W >> h >> w;    
 8     if((H/h)*(W/w)*(1000*(h*w-1)+1)>1000*(H*w-(H/h)*(W/w)))    
 9         cout << "No\n";
10     else{
11         cout << "Yes\n";
12         for(int i = 1; i <= H; i ++){
13             for(int j = 1; j <= W; j ++){
14                 if(i%h==0&&j%w==0) 
15                     cout << -1000*(h*w-1)-1 << ' ';
16                 else cout << 1000 << ' ';
17             }
18             cout << endl;
