%
% Simulate the effects of the MISO system defined by @var{th}.
% @var{e} is the noise in the input. It is scaled by @math{sqrt(v)}, where @var{v} is
% the noise variance given when you created the model, so for proper
% effect, @var{e} should have mean 0 and variance 1.
%
% If @var{e} is not given, then a noise free simulation is run.
