MATLAB: How to collect the results from a simulation for the model when I use the SIM command to run the model in Simulink 7.7 (R2011a)

simulink

I am running a Simulink model from a MATLAB script using the SIM command. In my model, I use 'To Workspace' blocks to log the simulation data outputs in the MATLAB workspace. I would like to collect these values from the MATLAB workspace once the simulation is completed.

The results from a simulation when using the SIM command are strored in an object of the class Simulink.Simulationoutputs.

In order to access these values, refer to the code below that can be used to access results from a simple simulation of a model with a 'To Workspace' block.

simOut = sim('vdp_ex', 'StopTime', '10');

workspace_struct = get(simOut, 'simout');

The 'workspace_struct' contains the fields of that are saved from the 'To Workspace' block. In order to access the values in this structure, I execute:

values = workspace_struct.signals.values;

Please execute the lines of code above agiainst the model that is attached to this solutionl.

Use set_param() on the appropriate blocks of the model to change the configuration of the model, and then sim() the model and record the results. For example,

gains = [1/10 1 2 5 10 50 100];
ngains = length(gains);
results = cell(ngains,1);
model_name = 'vdp';
block_name = 'vdp/Mu';
for K = 1 : ngains
    set_param(block_name, 'Gain', sprintf('%f', gains(K)));
    results{K} = sim(model_name);
end

The following code extracts all the logged variables from the model using the SIM function ans assign them to individual variables in the MATLAB workspace:

      clear
      mdl = 'mymodel';
      open_system(mdl)
      t_stop = 1.5;
      % Passing parameters to SIM using a structure
       paramStruct.StopTime = 't_stop';
       paramStruct.ReturnWorkspaceOutputs = 'on';
      % Simulate
      simOut = sim(mdl,paramStruct);
      %%Extract the logged signals
      % Obtain list of logged parameters
       paramList = simOut.who;
       % Loop through the list and assign in base workspace 
       for i= 1:length(paramList)
          assignin('base',paramList{i},simOut.get(paramList{i}));
       end
