Hi Přemysl,

Thanks for your report. I forwarded it to the octave mailing lists (Octave and 
OctaveForge) as it not only concerns me in my role as the maintainer of the 
control package. Please keep the mailing lists in Cc for future requests.

As control-2.2.5 installed by
pkg -forge install control
works, it looks like a problem with the Suse package of control-2.2.0. 
is_real_vector.oct is a compiled function, a kind of plugin for the octave 
interpreter. The Suse package could be missing it or Octave doesn't find it. 
Please ask the Suse maintainers to upgrade to control-2.2.5 and to fix their 
package. BTW: You can check the package by running the command test_control.

Note that yast is the installer of Suse. It is updated by the Suse people, not 
by OctaveForge authors. Therefore some packages might be missing or outdated.

You can find all Octave packages on the official OctaveForge website
http://octave.sourceforge.net/packages.php
or by
pkg list -forge

Try
pkg install -forge communications
pkg install -forge ga
