Here's the information in each .mat file.(metric, PF, Population)

What I want to do is to use information in .mat file as inputs (PF->PF, Population->PopObj), and store the output (Score->metric) for the following function.

Extension: I have many .mat files like this.How do I handle this in a batch?

D = 'path to folder where those files are saved';
S = dir(fullfile(D,'*.mat'));
N = natsortfiles({S.name}); % download from FEX
C = cell(1,numel(N));
for k = 1:numel(N)
T = load(fullfile(D,N{k}));
C{k} = NHV(T.Population,T.PF);
end
This imports all .mat files in the given folder, runs the function NHV on their contents, and stores the function outputs in the cell array C. To get the right file order you can download the function natsortfiles here:

Simpler:
parfor k = 1:10
F = sprintf('IDMOEAD/IDMOEAD_DSDTLZ1_M3_%d.mat',k);
S = load(F);
S.metric = NHV(S.Population.objs,S.PF);
save(F,'-struct','S');
end

For unknow reason, you can not use save() in parfor directly.
That is why I created a "redundant" function parsave().
