Multiple parameter sweep in parfor using rapid accelarator mode

I am looking at the below example model

   Mb_sweep            = Mb*(0.5:5:45.5);
iterations          = length(Mb_sweep);
for i = iterations:-1:1
    parameterSet(i) = Simulink.BlockDiagram.modifyTunableParameters(rtp, ...
                                                      'Mb',Mb_sweep(i));
end
simout(iterations)  = Simulink.SimulationOutput;

I am trying to address a similar problem but with a larger list of parameters. i.e. instead of just Mb as in the above case, i have 5 parameters ( i have around 20 parameters but limiting to 5 as an example here). I have a cell array with a list of parameters (param_list) and a parameter sweep matrix with all the 5 parameters for 100 iterations (param_values (5 by 20 matrix). So below is how it looks

 param_list ={a,b,c,d,e};
 param_values=[1,2,3,4,5;... 100 rows];

Is there an elegant way to update all the 5 parameters using modifyTunableParameters but without hard coding them? I feel that it is silly to have to hard code a long list of parameters.

Once the parameterSet is created, i will be using it in a parfor loop. So, please consider the parfor limitations while providing a solution.

The example you are referring to actually shows rapid accelerator execution with parfor. It does look like you might need to create a parameter set using a for loop for each simulation run.

Just out of curiosity, when you say

Is there an elegant way to update all the 5 parameters using modifyTunableParameters but without hard coding them? I feel that it is silly to have to hard code a long list of parameters.

Do you have desired workflow in mind?

Hi,

I used this example as it is directly available on the mathworks website. Not exactly sure what you mean by desired workflow.

The exercise i have in mind is

1. using modifyTunableParameters, set the parameter names and values for 15 parameters to run for 100 simulations.
2. I would then use this paramset to run paralllel simulations in parfor.

The question is if i can set the 15 parameters using a list of variables (param_list) and their corresponding values (param_values) for 100 simulations without hardcoding all the 15 variable names like

    parameterSet(i) = Simulink.BlockDiagram.modifyTunableParameters(rtp, ...
                                                      'Mb',Mb_sweep(i), Mc, Mc_sweep(i), Md, Md_sweep(i));

instead something like

   parameterSet(i) = Simulink.BlockDiagram.modifyTunableParameters(rtp, ...
                                                      param_list,param_values(i));
