fprintf bug?

[frank wang]

Hi,

While using Octave, I noticed a problem with fprintf. It maybe a bug and I need expert's opinion.

 

Here is the code it does not work. It will print the output to a file named e(fid); u is a complex number. In this example, it is u =  0.0044312 +  0.0044312i

 

fid = fopen('test_report.txt','w');
for (ii = 0:15)
ii
u 
   fprintf(fid,'%d     %f\n', ii, u);
end
fclose(fid)
 

If we add ; after u, then it will print the data to test_report.txt. Here is the code:

 

fid = fopen('test_report.txt','w');
for (ii = 0:15)
ii
u;
   fprintf(fid,'%d     %f\n', ii, u);
end
fclose(fid)
 

Thanks
