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
