a is a simple 2x2 matrix in octave. I save it as binary data in data.bin:

octave:42> save -binary data.bin a

Now I would like to open the file and read the data from outside octave. I tried to use liboctave (do_load() and read_binary_data()) following this example (http://wiki.octave.org/Fortran) but without success.

I use

do_load (file, fname, format, oct_mach_info::flt_fmt_unknown, false, false, true, argv, 0,` 1, 1);

I have an error with read_binary_data()

error: load: trouble reading binary file `data.bin'

The file is ok (I can load it from octave), so I guess I'm doing something wrong.. but what?

check the file pointer, does it point to an ifstream? is it null? – Lefteris E Jun 14 '13 at 13:19
also check the filename .. has it got the fullpath? – Goz Jun 14 '13 at 13:32
I tried to load an ascii file and it works.. This i guess excludes file pointer problems.. – nimig Jun 17 '13 at 10:47
