Hello!
Suppose we want to getl the following file: fid=fopen(pfmc100.dimacs, "r");
--- start file ---
a 5 4 0 5 -1
a 6 5 0 8 0
a 6 4 0 15 7
--- end file ---
> linea = getl(fid);
> [str de a l u c cnt] = sscanf(linea, '%s %i %i %i %i %i', "C");
c = -1
cnt = 6
> linea = getl(fid);
> [str de a l u c cnt] = sscanf(linea, '%s %i %i %i %i %i', "C");
c = [](0x0)
cnt = 5
> linea = getl(fid);
> [str de a l u c cnt] = sscanf(linea, '%s %i %i %i %i %i', "C");
c = 7
cnt = 6
That is, if the last number on a line is 0 (zero) it won't be correctly
read: c=[](0x0) with cnt=5. If it is other number/letter there is no problem
(cnt=6).
A work around is:
> [str de a l u c cnt] = sscanf(linea, '%s %i %i %i %i %s', "C");
c = str2num(c)
and worked as expected on the lines where the last item is a 0 (zero).
I am not sure this is the correct behaviour of getl(...).
Any comments?
Andres.
