Dear Joao, please dont hijack threads.

I'm not sure if I understand your question so please provide some smaple
matrix and your desired output.

Just a wild guess what you want:
octave:1> a=rand(4,3)*100, printf("%5.2f\t%.3f\t%.1f\n",a')
a =

   89.15902   73.22400   81.72654
   80.67683   52.45572   80.93744
   82.50297   43.73875   10.93027
   13.17486    0.15580    5.45265

89.16   73.224  81.7
80.68   52.456  80.9
82.50   43.739  10.9
13.17   0.156   5.5
