Details:


% requires the control package
s = tf ('s')

% works
[s, 0; 0, s]

% fails
[s, 0; 0, 1]
% error: octave_base_value::map_value(): wrong type argument 'scalar'
% error: octave_base_value::parent_class_name_list(): wrong type argument
'scalar'


the same result is obtained with the quaternion package if


s = quaternion (1)
