[Octave-bug-tracker] [bug #43613] fread() with a vector size doesn't return a shortened matrix when it hits EOF

[Andreas Weber]

Update of bug #43613 (project octave):

                  Status:                    None => Confirmed

Follow-up Comment #1:

I can confirm this behavior on the stable and default branch.

The problem is in oct-stream.cc around line 3451:
http://hg.savannah.gnu.org/hgweb/octave/file/8ba8f3d22189/libinterp/corefcn/oct-stream.cc#l3451


else if (count != nr * nc)
  {
    if (count % nr != 0)
      nc = count / nr + 1;

    if (count < nr)
      nr = count;
  }


which should be

  if (count % nr != 0)
    nc = count / nr + 1;
  else
    nc = count / nr;

  if (count < nr)
    nr = count;


to my understanding. If someone can confirm that Matlab behaves the way
described below, I'll prepare a patch and test for this issue.
