    _______________________________________________________

Details:

The function doesn't correctly perform the check on the system blocks
dimensions (see function documentation before proceeding).
The check should make sure that the 'feedout' indeces don't exceed the
dimension of the output of 'sys1', namely the forward block for the feedback
function. Instead, the function performs that check on the local variable
'feedin'.

What the function DOES:
/usr/share/octave/packages/control-2.3.52/@lti/feedback.m:line 131

if (any (feedin > p1 | feedin < 1))
%etc.
endif


What the function SHOULD DO:
/usr/share/octave/packages/control-2.3.52/@lti/feedback.m:line 131

if (any (feedout > p1 | feedout < 1))
%etc.
endif
