Hello,
I have a .mat file as following
Name adress company
BOB london BIM
Alfred Paris BOB
John BOB CEF
I would like to display only the duplicate variable in or order to create this new .mat file
Name adress company
BOB
BOB
BOB
If someone have an idea to create the adapted code?
Thanks in advance

common_values = intersect(intersect(Name, adress), company);
N = length(Name);
NName = strings(N, 1);
mask = ismember(Name, common_values);
NName(mask) = Name(mask);
Nadress = strings(N, 1);
mask = ismember(adress, common_values);
Nadress(mask) = adress(mask);
Ncompany = strings(N, 1);
mask = ismember(company, common_values);
Ncompany(mask) = company(mask);
output = table(Nname, Nadress, Ncompany, 'VariableNames', {'Name', 'adress', 'company'});

A = readtable('DataFilter.xlsx','TextType','string');
names_by_var = varfun(@unique, A, 'OutputFormat', 'cell');
[G, ID] = findgroups(categorical({names_by_var{:}}));
counts = accumarray(G, 1);
names_with_dups = ID(counts>1);
is_dup = varfun(@(V) ismember(categorical(V), names_with_dups), A, 'OutputFormat', 'uniform');
Aarray = table2array(A);
B = strings(size(Aarray));
B(is_dup) = Aarray(is_dup);
