I try to evaluate a simulink model in matlab. Therefor I use the matlab command sim(...). I found this two pages with some information:

http://de.mathworks.com/help/simuli.....sing-the-sim-command.html http://de.mathworks.com/help/simulink/slref/sim.html

and also some entries on stackoverlow. But there I found only partial solutions to my problem and combining them did not work.

Here a minimal example of my problem:

The simulink model has a single input parameter which is plugged directly to a output parameter. THe input parameter is called input, the output parameter is called output. This model is named 'minimal'. For simplicity this is all.

My matlab script looks like the following:

%%Set matlab specific variables:
slCharacterEncoding('Windows-1252');
%%Set parameter
input = 1;
%%Set simulation parameter
%steps = [step_first step_last];
%%Do simulation
mdl = 'minimal';
simMode = get_param(mdl, 'SimulationMode');
cs = getActiveConfigSet(mdl);
mdl_cs = cs.copy;
set_param(mdl_cs,'AbsTol','1e-5',...
         'SaveState','on','StateSaveName','xoutNew',...
         'SaveOutput','on','OutputSaveName','youtNew')
evalin('base','input=1');
options=simset('SrcWorkspace','base','DstWorkspace','base');
sim(mdl,[0 1],options)
disp(yout);
%%end
disp('Simulation ended.');
