Accessing parsim data in Matlab

Question

Good evening, May I please get advice with the following Matlab code? Here it is:

%% CLEAR ALL
close all
clear all
clc
%% LOAD MODEL AND LHC FILE
tic %start the clock
idx=1;
model = 'PG_PN_basic_rev1'; %This is the simulink file you wish to run.
load_system(model);
load 'LHC_input.mat' %Call in the file created by LHC_Final.m
LHC = (LHC1_input);
k_dc = LHC((1:5),1);
k_r = LHC((1:5),2);
a_1 = LHC((1:5),3);
b_1 = LHC((1:5),4);
Kg_PG = LHC((1:5),5);
Kg_PN = LHC((1:5),6);

for i = length(k_dc):-1:1
in(i) = Simulink.SimulationInput('PG_PN_basic_rev1');
in(i) = in(i).setVariable('k_dc',k_dc(i));

    for j = length(k_r):-1:1
    in(j) = in(j).setVariable('k_r',k_r(j));

        for k = length(a_1):-1:1
        in(k) = in(k).setVariable('a_1',a_1(k));

            for l = length(b_1):-1:1  
            in(l) = in(l).setVariable('b_1',b_1(l));
    
                for m = length(Kg_PG):-1:1
                in(m) = in(m).setVariable('Kg_PG',Kg_PG(m));

                    for n = length(Kg_PN):-1:1
                    in(n) = in(n).setVariable('Kg_PN',Kg_PN(n));
            
                    end
                end
            end
        end
    end
end
out = parsim(in, 'ShowProgress', 'on');
% eval(['PN_batch', int2str(idx),' =PN;']);
% data = eval(['PN_batch', int2str(idx)]);
% a{idx} = data;
% idx=idx+1;
% run = idx
timeElapsed = toc %How long did you code run for?

I wish to be able to generate an output file per parsim run (PN_batch1, PN_batch2,...etc.). However, the data often falls under just 1 output, and isn't divided up into readable workspace objects that I can read later with another script. Any advice would be greatly appreciated. Thank you.

out is a vector of length equal to the number of simulations with the data of a simulation stored in each entry. If you have to workspace blocks in your model, you can access that data per simulation using out(10).NameOftoWorkspaceData, in case you want to get the data of the 10th simulation. More info on the out variable can be found here on the Mathworks site.

Tip: run the model and check out the variable out, then you can explore its structure
