        4  0.000000       0.000000       2.000000
        5  0.000000       11.000000       4.000000
        6  0.000000       12.000000       4.000000

          3  0.000000         0.000000       1.000000
          4  0.000000         0.000000       2.000000
          5  0.000000        11.000000       4.000000
          6  0.000000        12.000000       4.000000
          7  0.000000        13.000000       4.000000
          8  0.000000        14.000000       4.000000
          9  0.000000        15.000000       4.000000
         10  0.000000        16.000000       4.000000
         11  0.000000        17.000000       4.000000

I am guessing that unlike your example you actually want the columns to be aligned, e.g. where M is your matrix:
>> fprintf(' %9d %9.6f %15.6f %15.6f\n',M.')
         1  0.000000        0.000000        0.000000
         2  0.000000        0.000000        4.000000
         3  0.000000        0.000000        1.000000
         4  0.000000        0.000000        2.000000
         5  0.000000       11.000000        4.000000
         6  0.000000       12.000000        4.000000
         7  0.000000       13.000000        4.000000
         8  0.000000       14.000000        4.000000
         9  0.000000       15.000000        4.000000
        10  0.000000       16.000000        4.000000
        11  0.000000       17.000000        4.000000
        12  0.000000       18.000000        4.000000
        13  0.000000       12.000000        0.000000
