 N=10
for i=1:N
format shortg
        tmp =  clock;
        out(i,:) = tmp([5,6])
end
in_zone=nonzeros(zone);
out =
           35        8.347
           35        8.351
           35        8.355
           35        8.359
           35        8.362
           35        8.366
           35         8.37
           35        8.376
           35        8.379
           35        8.383
           35        8.387
           35         8.39
           35        8.393
           35        8.396
           35          8.4
 in_zone =
     2
     3
     4
     6
     8
    10

now i wish to store the out value acooarding to in_zone value in the array example below

new_array=

    35        8.351
    35        8.355
    35        8.359

Do not place the format call inside the loop! format only needs to be called once and its new setting will apply to the entire MATLAB session. Read more about it in the documentation:

http://www.mathworks.com/help/matlab/ref/format.html

Also note that you should not use i or j as variable names, as these are both names of the inbuilt imaginary unit.
