Matrix 90 Grad drehen



  • Does anyone know a better algorithm to turn a matrix by 90 degrees.

    public class TurnMatrix {
    
    	final int[][] mat = new int[][]{{1,2,3},{4,5,6},{7,8,9}};
    	int[][] matNew = new int[3][3];
    
    	public void turnMatrix90()
    	{
    
    		for(int i=0,k=2;i<3;i++,k--)
    		{
    			for(int j =0;j<3;j++)
    			{
    				matNew[j][k]=mat[i][j];
    			}
    		}
    
             // print matNew
    	}
