Re: fprintf bug?

[frank wang]

I just test it in another machine and found the code works. Then I found out the failure was caused by copy the code from vi editor.  If I copy the all code, then press the middle mouse to paste it into octave, it will not work as before. But if I copy the code without the last fclose(fid), then paste it into ocatve, hit return and type fclose(fid). It works.

 

Thanks

It does not work in my setting. I am using 2.9.7. I just run it and u=1. I got the last few lines:

 

u =  1

ii =  14
u =  1
ii =  15
u =  1

Badly placed ()'s.
 

And the output file is e(fid). All output correctly printed in this file e(fid).

 

I will try it in another machine.

 

Thanks

I see some bug with 2.9.7.
If I do not put ";" after u (in my case u = 1) I get this junk:
...
ii =  14
u =  1
ii =  15
u =  1
