The current latest code seems to omit the “ys” parameter when calling \*\_steadystate in evaluate\_likelihood. Is this deliberate?

Passing oo\_.steady\_state is useful when there’s no analytic solution since it gives a base from which to start fsolve.

What would be particularly useful would be if they were all called with the return of the \*\_steadystate function from the previous call, rather than the auxiliary variable expanded version.

E.g.:

```auto
		if ~isfield( oo_, 'reduced_steady_state' )
			if isfield( M_, 'orig_endo_nbr' )
				NumberOfEndogenousVariables = M_.orig_endo_nbr;
			else
				NumberOfEndogenousVariables = M_.endo_nbr;
			end
			oo_.reduced_steady_state = zeros( NumberOfEndogenousVariables );
		end
		[ys,tchek] = feval([M_.fname '_steadystate'],oo_.reduced_steady_state,...
							   [zeros(M_.exo_nbr,1);...
								oo_.exo_det_steady_state]);
		oo_.reduced_steady_state = ys;
```
