There are many ways to do this, but I can quickly show you two:

```d
import std.stdio;
void main()
{
     int[][] matrix;
     enum n = 6;

     // method 1:
     //matrix = new int[][](n, n); /*

     // method 2:
     matrix.length = n;
     foreach(ref e; matrix)
         e.length = n;//*/
     
     matrix.writeln;
}
```
