% If the input names and output names (each a list of strings)
% are not given and the scaling matrices
% are not square, then default names will be given to the inputs and/or
% outputs.

% A warning message is printed if outscale attempts to add continuous
% system outputs to discrete system outputs; otherwise @var{yd} is
% set appropriately in the returned value of @var{sys}.
