This can now be closed.
damp.m is now in control-3.1.0

I don't want to be impatient or rude, but is anybody actually reviewing these files in the patch tracker?
I know this is an open source project and you are working on this in your free time, but I submitted this almost 5 months ago and reviewing and merging the code shouldn't take long.

It would be nice to get a short reply, so I know that it's worth the effort (since there are some more functions I would like to work on).

That said, I really enjoy Octave and its Control package!

In the lastest file submission, I re-formatted the code to follow Octave's style guide more closely (only cosmetic changes). --Mark

Any news/feedback on this one?
Do you want me to change anything? It should be ready to be merged though...
Please note that one test will fail unless my other "pole.patch" submission (https://savannah.gnu.org/patch/index.php?9255) is applied.

## Calculate natural frequencies, damping ratios and poles.
##
## If no output is specified, display overview table containing poles, magnitude
## (if @var{sys} is a discrete-time model), damping ratios, natural frequencies
## and time constants.
##
## @strong{Inputs}
## @table @var
## @item sys
## @acronym{LTI} model.
## @end table
##
## @strong{Outputs}
## @table @var
## @item Wn
## Natural frequencies of each pole of @var{sys} (in increasing order).
## The frequency unit is Hz (reciprocal of a second).
## If @var{sys} is a discrete-time model with specified sample time, @var{Wn}
## contains the natural frequencies of the equivalent continuous-time poles
## (see Algorithms). If @var{sys} has an unspecified sample time
## (@var{tsam =} -1), @var{tsam =} 1 is used to calculate @var{Wn}.
## @item zeta
## Damping ratios of each pole of @var{sys} (in the same order as @var{Wn}).
## If @var{sys} is a discrete-time model with specified sample time, @var{zeta}
## contains the damping ratios of the equivalent continuous-time poles
## (see Algorithms). If @var{sys} has an unspecified sample time
## (@var{tsam =} -1), @var{tsam =} 1 is used to calculate @var{zeta}.
## @item P
## Poles of @var{sys} (in the same order as @var{Wn}).
