In a program I have following result for 'Check' variable
>>Check=[testing_ind' ldaClass  All_data(testing_ind,:)];
>>Check =
    9.0000    1.0000    1.4000    0.2000
   32.0000    1.0000    1.5000    0.4000
   33.0000    1.0000    1.5000    0.1000
   34.0000    0.0000    1.4000    0.2000
   35.0000    0.0000    1.5000    0.2000
But I want the output like this
>>Check =
    9    1    1.4000    0.2000
   32    1    1.5000    0.4000
   33    1    1.5000    0.1000
   34    0    1.4000    0.2000
   35    0    1.5000    0.2000
How to do this?

        Use fprintf() to specify how many decimal places you want when you print stuff out.
Check =[...
    9.0000    1.0000    1.4000    0.2000
   32.0000    1.0000    1.5000    0.4000
   33.0000    1.0000    1.5000    0.1000
   34.0000    0.0000    1.4000    0.2000
   35.0000    0.0000    1.5000    0.2000]
for k = 1 : size(Check, 1)
  fprintf('%4d   %4d   %.4f  %.4f\n', Check(k,1),Check(k,2),Check(k,3),Check(k,4));
end
Results in command window:
     9      1   1.4000  0.2000
    32      1   1.5000  0.4000
    33      1   1.5000  0.1000
    34      0   1.4000  0.2000
    35      0   1.5000  0.2000
