How to display sprintf in a 'for' loop in static text of GUI?

Greetings. I wish to display a sprintf output as in command window. The output should look like this:

My goal is to display the same output in my GUI static text box, but my code couldn't work.

The function rk3 is runge-kutta 3rd order:

E1=rk3(f,df,a,b,ya,M);
for j=1:M+1
    message1 = message1 + sprintf('%5d %10.5f %10.5f %10.5f\n' , E1(j,1) , E1(j,2) , E1(j,3) , E1(j,4));
end
set(handles.text8,'String',message1);

Your help is much appreciated. Thanks!!

Whenever you mention "did not work" in the forum, add the complete error message or explain the difference between the results and your expectations. Do not let the readers guess, what's going on.

You cannot add strings by "A+B" in Matlab. Use "[A, B]" instead.

The loop is not required:

message = sprintf('%5d %10.5f %10.5f %10.5f\n' , E1.');    % Or: E1(1:M+1, 1:4).'

Hi. Thank you very much for the answer. Truly appreciate it! Sorry for the mistake. I will surely post the error message next time.

However, I would need another help, which I wish to make the output neat, which looks like this:

I have tried using the 'format short' and '%1d' in my code.

Sorry for making the change. Thanks :)

format short has effects in the command line only. Where do you tried "%1d"? Is your problem the "0" in the first place? There is not output format which removes the decimals for 0 only. If you need this, you have to prgram a small workaround by your own.

If you post the text as text and not as screen shot, working with the data is easier.

Hi, I tried %1d in here

message = sprintf('%1d %10.5f %10.5f %10.5f\n' , E1.');

but I solved it using

message = sprintf('%.2f %10.5f %10.5f %10.5f\n' , E1.');

Thanks :D

How about this?

fprintf('%s       %s         %s      %s   \n','t','Ytrue','Yrk3' ,'|Et|%')
for i = 1:5
    fprintf('%f  %f  %f %f   \n',rand(1),rand(1),rand(1),rand(1))    
end
