print to screen with fromat

Hello,

I am trying to print to screen results that come in the form of lines of numbers. I woul like to have the numbers aligned by the decimal dot.

I am using the following code

obj_str=[num2str(igor) '\t '  datestr(now) '\t'  num2str(x(:)','%15.3f') '\t'  num2str(qt,'%15.3f') '\n'];
fprintf(1,obj_str)

and I am getting the following output

1 10-Sep-2022 09:16:46 45.000 3.000 1.000 3.850 5.200 11.250 9.300 -0.042 18.456 51.792

2 10-Sep-2022 09:19:36 108.534 21.049 2.992 13.570 19.652 15.646 40.301 -0.004 4.129 26.957

3 10-Sep-2022 09:22:04 120.696 8.583 3.779 17.084 14.070 52.112 24.315 -0.295 -3.247 20.601

4 10-Sep-2022 09:24:52 81.327 20.654 4.337 18.853 22.594 16.111 23.815 -0.003 7.905 37.148

I would like to get an output simular to this

1 10-Sep-2022 09:16:46 45.000 3.000 1.000 3.850 5.200 11.250 9.300 -0.042 18.456 51.792

2 10-Sep-2022 09:19:36 108.534 21.049 2.992 13.570 19.652 15.646 40.301 -0.004 4.129 26.957

3 10-Sep-2022 09:22:04 120.696 8.583 3.779 17.084 14.070 52.112 24.315 -0.295 -3.247 20.601

4 10-Sep-2022 09:24:52 81.327 20.654 4.337 18.853 22.594 16.111 23.815 -0.003 7.905 37.148

Using only the posted data —

C = {1	 '10-Sep-2022 09:16:46'	45.000    3.000    1.000    3.850    5.200   11.250    9.300	-0.042   18.456   51.792

fileID = 1;
for k = 1:size(C,1)
    fprintf(fileID,['%d   %s ' repmat('%15.3f',1,10) '\n'], C{k,:})
end
