[Octave-bug-tracker] [bug #41672] fread for "float" not matlab compatible

[Mike Miller]

Update of bug #41672 (project octave):

                  Status:                    None => Need Info

Follow-up Comment #3:

This seems to be the case, the docs for fread/fwrite don't seem to distinguish
between platform types.

Someone could verify by running the following in Matlab on 64-bit Windows:


fid = fopen('test.dat', 'wb');
fwrite(fid, int64(-1), 'int64');
pos = ftell(fid)
fclose(fid);
fid = fopen('test.dat', 'rb');
arr = fread(fid, inf, 'long')
pos = ftell(fid)
fclose(fid);


In 64-bit Octave, arr is a one-element array of -1, but in 64-bit Matlab it
may be a two-element array of -1.
