[Octave-bug-tracker] [bug #38870] load reads stochastic data from MAT -file

[anonymous]

Follow-up Comment #8, bug #38870 (project octave):

The program is an in-laboratory code, which is not distributed to any other
place. In such, the trouble is local. I think I am the first one who has tried
to use the output in Octave.

However, I noticed that xxxxxxx and yyyyyy variables had no trouble loading
correctly all the time. The trouble is with the single letter names.

I went through the ls-mat5.cc and I think the problem is line 
696 (reading variable name):

is.seekg (tmp_pos + static_cast<std::streamoff> (PAD (len)));

PAD is defined as (len > 0 && len <= 4) ? 4 : ((l+7)/8)*8; For the 1 char
variables this gives padding of 4 and not proper 7. The padding should here be
just ((l+7)/8)*8 without the iffing (and probably in a few other places where
small data fragments might occur).

This also explains why the parser sees the "type" as 0 (padding) instead of 9
(and the 9 will become data length).

Could either of you check this out? I don't have source code of Octave nor
idea how to get a version.
