Hey everybody,

so I have a Simulink simulation where I vary a parameter

for i=1:length(parameter)
 Input_var=parameter(i)
 sim(modelname)     
 simout_store(:,i)=simout(:,1) %simout is a "to workbench" output in the simulation
end

But all I get is this error "Subscripted assignment dimension mismatch." How can I fix this? I just want to save the results after every simulation before it gets overridden

Use a cell array

simout_store{i}=simout(:,1)

If the step time is not fixed, you can get any number of samples

Jepp that will be the problem...

set_param(modelname,'SolverType','Variable-Step');
set_param(modelname,'maxstep','0.0015');
set_param(modelname,'minstep','auto');
set_param(modelname,'Solver','ode23s');
set_param(modelname,'StartTime','0');
set_param(modelname,'StopTime','10');
