Missing is_real_vector and is_real_matrix

[Thomas Reinemann]

Hello,

I installed octave yesterday and tried to use the tf function. But I
alway receive an error message like

octave:3> sys = tf (n, d)
error: `is_real_vector' undefined near line 38 column 15
error: called from:
error:   /usr/share/octave/packages/control-2.0.1/@tfpoly/tfpoly.m at
line 35, column 7
error:   /usr/share/octave/packages/control-2.0.1/__vec2tfpoly__.m at
line 32, column 7
error:   /usr/share/octave/packages/control-2.0.1/@tf/tf.m at line 123,
column 5


A search in the installation directory showed that the function is used
in many places. But there isn't a function which provides
is_real_vector. The same is true for is_real_matrix.

Which package contains both functions?

I use OpenSuse 11.2 and installed via the OpenSuse

download.opensuse.org/repositories/science/openSUSE_11.2/

repository.

Thanks Tom
