How to cache data while in for loop

Hey everybody,

so I have a Simulink simulation where I vary a parameter

for i=1:length(parameter)

    Input_var=parameter(i)                 % input for simulation
    sim(modelname)                         % simulate  the model
    sim_out_store(:,i)=sim_out(:,1)        % sim_out 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 in the next loop cycle.

Probably sim_out is sometimes empty. You cannot store empty results in a numeric array. Use a cell array instead.

sim_out_store{i} = sim_out(:,1);
