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:
