Name    = { 'Mert', 'Jack' , 'Jimmy' , 'John' };
Surname = { 'Dogan', 'Surname' , 'Surname' , 'Surname'};
Pattern = { 'How','Can','Do,'This'};
trynumber = 1:3;

Folder = cd;  % Set accordingly
for iName = 1:numel(Name)
  for iPattern = 1:numel(Pattern)
    for iTry = 1:numel(trynumber)
      Filename = fullfile(Folder, sprintf('%s_%s_%s_%d.fmt', ...
          Name{iName}, Surname{iName}, Pattern{iPattern}, trynumber(iTry));
      tree = load_file(Filename);
      ...
    end
  end
end
