And what version of Octave?

I have been told odepkg does not work with current
Octave releases (4.2.x) ...

Anyway it would be helpful if you could check whether the same problem also applies to odepkg 0.9.1 which is as of yet unreleased.

If you are using Octave 4.2.x you can install
a development snapshot as follows:

[fname, success] = urlwrite ("https://bitbucket.org/odepkg/odepkg/get/default.tar.gz", [P_tmpdir "odepkg.tar.gz"]);
assert (success)
pkg ("install", fname)

If you are using the development version of Octave you can use
[fname, success] = urlwrite ("https://bitbucket.org/odepkg/odepkg/get/octave43.tar.gz", [P_tmpdir "odepkg.tar.gz"]);
assert (success)
pkg ("install", fname)

If you have an older version of Octave please upgrade before trying this.

thanks again!

Hi, thanks for the report!
What version of odepkg did you test?

One of the unit tests in file odepkg_testsuite_calcmescd.m has a wrong expected value:

%!assert (odepkg_testsuite_calcmescd ([1, 2, 3], [1, 2, 3], NaN, NaN), Inf);

It should be actually:

%!assert (odepkg_testsuite_calcmescd ([1, 2, 3], [1, 2, 3], NaN, NaN), NaN);
