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
14 0.000000 11.000000 0.000000
